Bug Authentication fails with Invalid Token

The last week the auth sdk was working fine.
Today I let my editor active and returend to my pc 3-4 hours later.
When I hit play i get:

Code (CSharp):

1. [Authentication]: Request completed with error: {"title":"INVALID_SESSION_TOKEN","detail":"The session token is not valid.","details":[],"status":401}
2.  
3. UnityEngine.Logger:LogWarning (string,object)
4. Unity.Services.Authentication.Utilities.Logger:LogWarning (object) (at Library/PackageCache/com.unity.services.authentication@1.0.0-pre.37/Runtime/Utilities/Logger.cs:16)
5. Unity.Services.Authentication.Utilities.WebRequest:RequestCompleted (System.Threading.Tasks.TaskCompletionSource`1<string>,long,bool,bool,string,string,System.Collections.Generic.IDictionary`2<string, string>) (at Library/PackageCache/com.unity.services.authentication@1.0.0-pre.37/Runtime/Utilities/WebRequest.cs:209)

When I restart the editor the issue persists.
Now I wonder if this is something that could also happen to a client of the final app. (customer)

 

unity_Ctri

yes thanks. So we are still in development nothing is live yet. My user ID I can send you.
For now we only use anonymous and I would like this one to work withouth issues aswell for those players that never link.

Does it maybe occure because I have the sign-In in a singleton which is "DontDestroyOnLoad"?
The user persisted even when hitting play mode again and again.
And theoratically recal await SignInAnonymously(); every time.
But it didnt seem to create a new one.

So is there a way to check if I currently already have a session token and check if its still valid? (or should i try catch it?)
How ever this still leaves me with the questio what to do with an invalid token when SignInAnonymoulsy does not overwrite it.

 

sent a pm!
(restarting the pc does not fix that issue)
Just information for others in future:
I use a singletone with dont destroy on load which maybe particpates to this issue.

 

Hi Erick,

thanks for looking into this issue:

"com.unity.services.cloudcode": "1.0.0-pre.6",
"com.unity.services.authentication": "1.0.0-pre.37",
"com.unity.services.cloudsave": "1.0.0-pre.3"


cloudProjectId: abfb5932-efea-4a54-814b-6c42e1b95645

 

Session Id i can find via registry

abfb5932-efea-4a54-814b-6c42e1b95645.default.unity.services.authentication.session_token_h3622902611

 

@erickboulay

Any news on that issue?
I still have auth commented out in our code as it still has the issue with the corrupted session token.

Code (CSharp):

1.    //   await SignInAnonymously();

 

Thanks
here the output of the debug.log

(AuthenticationService.Instance.ClearSessionToken)
worked

yeah I realized that anonym users are refered as their session token.
So everytime I get a new session token the data is not longer coupled to the player, which has not changed his device.

Session token 1:
7oBGbe6Wys2BBokd6AwuTLbOrwMl

Session token2:
GkNbHbIi6aMX5CW3WLOH7F8VNWGB

Etc


The expected behaviour would be:
Use an Id that is couple with the device ID. So even if a new session has to be created that user still has access to his data aslong he uses the same device.

 

Thank you

 

Hello, I ave exactly the same issue in the player while testing (when testing on devices it works). What is the procedure to have the player authenticating again ?

 

Thank you very much. It worked nicely (actually clearing the playerprefs didn't, but the clearing the token in code worked). As you mentioned at the beginning this token is supposed to be reinitialized at each start, is it good practice to keep AuthenticationService.Instance.ClearSessionToken in the code to be executed each time and force the reinitialization of the token in case it's blocked ?

 

Ok, thank you very much.

 

Hi all, I know this is an old thread but facing the same issue in my game implementation. When i use SignInAnonymouslyAsync() and hit play the user get logged in successfully, but when stop the game and start it again it creates a new user and the old access token gets empty. i am using the below sample code for anonymous login.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using System.Threading.Tasks;
4. using Unity.Services.Authentication;
5. using Unity.Services.Core;
6. using UnityEngine;
7.  
8. public class Authentication : MonoBehaviour
9. {
10.     internal async Task Awake()
11.     {
12.         await UnityServices.InitializeAsync();
13.         await SignInAnonymously();
14.     }
15.  
16.     private async Task SignInAnonymously()
17.     {
18.         Debug.Log(AuthenticationService.Instance.AccessToken);
19.         AuthenticationService.Instance.SignedIn += () =>
20.         {
21.             var playerId = AuthenticationService.Instance.PlayerId;
22.  
23.             Debug.Log("Signed in as: " + playerId);
24.         };
25.         AuthenticationService.Instance.SignInFailed += s =>
26.         {
27.                 // Take some action here...
28.                 Debug.Log(s);
29.         };
30.  
31.         await AuthenticationService.Instance.SignInAnonymouslyAsync();
32.     }
33. }
34. }

 

Hi @erickb_unity , I get this error when I try re-login after logout: Unity.Services.Authentication.AuthenticationException: unable to validate token ---> Unity.Services.Authentication.WebRequestException: {"title":"PERMISSION_DENIED","detail":"unable to validate token","details":[],"status":401}. Help me fix this please

 

I use PlayGamesPlatform.Instance.ManuallyAuthenticate instead of PlayGamesPlatform.Instance.Authenticate. Now I can logout and re-login success every time

 

Hi i am using anonymous login and it is working perfectly, i got userid, accesstoken etc, and i have stored them in a playerpref too, but my question is how can i relogin someone with same details . As i am using unity leaderboard and it is saying: LeaderboardsException: Access token is missing - ensure you are signed in through the Authentication SDK and try again.

It happen after i close the game and run it again.

 

What’s your sign in flow looking like? What do you use to sign in? When do you call the leaderboard service?

 

For SignIn i have two option :
1. Anonymous
2. Google play games login

I want to use them with Unity Cloud.
Now after successfull login when i load leaderbord it works fine , but after closing the game it does not works , here is my code:

Code (CSharp):

1. using System.Threading.Tasks;
2. using Unity.Services.Authentication;
3. using Unity.Services.Core;
4. using UnityEngine;
5. using UnityEngine.SceneManagement;
6. public class splashScript : MonoBehaviour
7. {
8.     public static splashScript instance;
9.     public GameObject loginOption;
10.     public GameObject loadingTxt;
11.     public GameObject loadingScreen;
12.  
13.     private void Awake()
14.     {
15.         instance = this;
16.         Init();
17.     }
18.     async void Init()
19.     {
20.         await UnityServices.InitializeAsync();
21.     }
22.     private void Start()
23.     {
24.          checkForLogin();
25.     }
26.     public void checkForLogin()
27.     {
28.         if (string.IsNullOrEmpty(PlayerPref.GetString("userIdPref")))//not log in
29.         {
30.             loginOption.SetActive(true);
31.             loadingTxt.SetActive(false);
32.         }
33.         else {
34.             loginOption.SetActive(false);
35.             loadingTxt.SetActive(true);
36.          
37.             Invoke(nameof(LaunchGame),1f);
38.         }
39.     }
40.     void LaunchGame() {
41.         SceneManager.LoadScene(1);//in that scene i am loading leaderboard, which will work fine if i am properly authenticated, so i think error is in this script only
42.     }
43.  
44.     public async void SignInAnonymous()// call by click of a button in scene
45.     {
46.         await signInAnonymous();
47.     }
48.     async Task signInAnonymous()
49.     {
50.    
51.         // Check if a cached player already exists by checking if the session token exists
52.         if (AuthenticationService.Instance.SessionTokenExists)
53.         {
54.             // if not, then do nothing
55.             print(AuthenticationService.Instance.PlayerId);
56.             return;
57.         }
58.         // Sign in Anonymously
59.         // This call will sign in the cached player.
60.         try
61.         {
62.             await AuthenticationService.Instance.SignInAnonymouslyAsync();
63.             Debug.Log("Sign in anonymously succeeded!");
64.             print("Player Id:" + AuthenticationService.Instance.PlayerId);
65.          
66.          
67.             PlayerPref.SetString("userIdPref", AuthenticationService.Instance.PlayerId);
68.        
69.             checkForLogin();//now leaderboard will work fine, as i just logged in, but not work next time
70.          
71.         }
72.         catch (AuthenticationException ex)
73.         {
74.          
75.             print("Sign in failed!!"+ex);
76.         }
77.         catch (RequestFailedException ex)
78.         {
79.        
80.             print("Sign in failed!!"+ex);
81.         }
82.     }
83.  
84. }

i hope you understand the problem from my code, my only problem is, how can i login a user if i already have access token from previous successfull signin.

 

You still need to call SignInAnonymously to get a fresh token and sign the player in. Imagine the player doesn’t pay for several weeks, a token will never be valid for such a long time.

 

Hi i just updated my code a little , now i am checking if sessionTokenExsist or not, please have a look

Code (CSharp):

1. using System.Threading.Tasks;
2. using Unity.Services.Authentication;
3. using Unity.Services.Core;
4. using UnityEngine;
5. using UnityEngine.SceneManagement;
6.  
7. public class splashScript : MonoBehaviour
8. {
9.     public static splashScript instance;
10.  
11.     public GameObject loginOption;
12.     public GameObject loadingTxt;
13.     public GameObject loadingScreen;
14.  
15.  
16.     private void Awake()
17.     {
18.         instance = this;
19.         Init();
20.     }
21.     async void Init()
22.     {
23.         await UnityServices.InitializeAsync();
24.     }
25.     private void Start()
26.     {
27.        checkForLogin();
28.     }
29.  
30.     public void checkForLogin()
31.     {
32.        
33.  
34.         if (AuthenticationService.Instance.SessionTokenExists)
35.         {
36.             print("token exsist: "+ AuthenticationService.Instance.PlayerId);
37.             loginOption.SetActive(false);
38.             loadingTxt.SetActive(true);
39.             Invoke(nameof(LaunchGame), 1f);//Launching game
40.         }
41.         else {
42.             print("No token");
43.             loginOption.SetActive(true);
44.             loadingTxt.SetActive(false);
45.         }
46.     }
47.  
48.  
49.     void LaunchGame() {
50.         SceneManager.LoadScene(1);
51.     }
52.  
53.  
54.     public async void SignInAnonymous()
55.     {
56.         await signInAnonymous();
57.     }
58.  
59.     async Task signInAnonymous()
60.     {
61.      
62.         // Check if a cached player already exists by checking if the session token exists
63.         if (AuthenticationService.Instance.SessionTokenExists)
64.         {
65.             // if not, then do nothing
66.             print("previous player:  "+AuthenticationService.Instance.PlayerId);
67.             SavedDataScript.SetValueString(SavedDataScript.userIdPref, AuthenticationService.Instance.PlayerId);
68.  
69.             checkForLogin();
70.             return;
71.         }
72.  
73.         // Sign in Anonymously
74.         // This call will sign in the cached player.
75.         try
76.         {
77.             await AuthenticationService.Instance.SignInAnonymouslyAsync();
78.             Debug.Log("Sign in anonymously succeeded!");
79.  
80.             print("Player Id:" + AuthenticationService.Instance.PlayerId);
81.             string accessToken = AuthenticationService.Instance.AccessToken;
82.             SavedDataScript.SetValueString(SavedDataScript.userNamePref, "Tester" + Random.Range(000, 999));
83.             SavedDataScript.SetValueString(SavedDataScript.userIdPref, AuthenticationService.Instance.PlayerId);
84.             SavedDataScript.SetValueString(SavedDataScript.accessToken, accessToken);
85.  
86.             checkForLogin();
87.             // logTxt.text = "Player id:" + AuthenticationService.Instance.PlayerId;
88.         }
89.         catch (AuthenticationException ex)
90.         {
91.             // Compare error code to AuthenticationErrorCodes
92.             // Notify the player with the proper error message
93.             // Debug.LogException(ex);
94.             print("Sign in failed!!"+ex);
95.  
96.         }
97.         catch (RequestFailedException ex)
98.         {
99.             // Compare error code to CommonErrorCodes
100.             // Notify the player with the proper error message
101.             //Debug.LogException(ex);
102.             print("Sign in failed!!"+ex);
103.  
104.         }
105.     }
106.  
107. }
108.  

Now in my next scene where i show the data in leader board , it still throwing an error , even when my session token exsist .

error:
LeaderboardsException: Access token is missing - ensure you are signed in through the Authentication SDK and try again.
Unity.Services.Leaderboards.Internal.LeaderboardsApiClientInternal.ValidateRequiredDependencies

Code (CSharp):

1. public void ShowLeaderboard() {
2.     loadingLeaderboard.SetActive(true);
3.     leaderboardUi.SetActive(true);
4.     GetScores();
5. }
6. public async void GetScores()
7. {
8.     var scoresResponse = await LeaderboardsService.Instance
9.         .GetScoresAsync(leaderboardId);
10.     Debug.Log(JsonConvert.SerializeObject(scoresResponse));
11.     lData = JsonUtility.FromJson<leaderboardData>(JsonConvert.SerializeObject(scoresResponse));
12.     loadingLeaderboard.SetActive(false);
13.  
14.     UpdateLeaderboard();
15. }

I hope you understand my problem

 

You fundamentally don’t understand how authentication works, sorry. You need to sign in every time you start the game! You don’t need to store an access token, the SDK already does this for you. Simply, before invoking the game scene, call SignInAnonymously.

 

Got it working, Thanks,
One last thing, After successfull login can we see the list of users in unity dashboard , just like we can see in firebase.
As i am unable to find a option in unity cloud under authentication


like this

 

In the Unity dashboard, go to Live Ops, Authentication and then Player Management.

 

Hi guys, I have this issue. I want to make Sign in with a special ID by
AuthenticationService.Instance.ProcessAuthenticationTokens. But it always returns this error "[Authentication]: That is not a valid token (expected 3 parts but has 1).".
So how can I create a token with my string value, thanks!
