Resolved Token Null with Player Accounts

Hello. I'm running into an issue with Player Accounts and tokens. When the game starts I initialize gaming service and call the StartSignInAsync function. The window pops up and I sign in, everything seems successful. The issue comes when I try to pull some cloud save data. My cloud save pull was working when I was just signing in anonymously but since I've added the Player Account sign in I'm getting an error (CloudSaveException: Access token is missing).

I spent some time reviewing the Player Accounts sample to see what I was doing wrong and I realized that when I tried to use the 'refresh token' button in the sample scene I was getting an error there too (PlayerAccountsException: Refresh token is null or empty).

Given that I didn't change anything in the sample scene and I'm getting the error I'm inclined to believe I have some kind of mistaken in my project setup but I have no idea what it would be. I have some of my code below. I greatly appreciate any assistance.

Code (CSharp):

1.    
2.  
3. private async void Start()
4.     {
5.         await UnityServices.InitializeAsync();
6.         signInWithUnity();
7.         PlayerAccountService.Instance.SignedIn += signInWithUnity;
8.     }
9.  
10.     async void signInWithUnity()
11.     {
12.         if (!PlayerAccountService.Instance.IsSignedIn)
13.         {
14.             try
15.             {
16.                 await PlayerAccountService.Instance.StartSignInAsync();
17.                 Debug.Log("Signed in " + AuthenticationService.Instance.PlayerId);
18.                 Debug.Log(AuthenticationService.Instance.AccessToken);
19.                 GetComponent<BattlePassCode>().checkPurchaseStatusOnCloud();
20.             }
21.             catch (AuthenticationException ex)
22.             { Debug.LogException(ex); }
23.             catch (RequestFailedException ex)
24.             { Debug.LogException(ex); }
25.         }
26.     }

Code (CSharp):

1.     public async void checkPurchaseStatusOnCloud()
2.     {
3.         Dictionary<string, string> savedData = await CloudSaveService.Instance.Data.LoadAsync(new HashSet<string> { "hasBattlePass" });
4.  
5.         if (savedData.ContainsKey("hasBattlePass"))
6.         {
7.             if (savedData["hasBattlePass"] == "true")
8.             { purchased = true; }
9.         }
10.     }

 

Thanks for the quick response Erick. Unfortunately I'm still having issues. I tried rolling your code into mine and I'm getting more errors. Perhaps I'm not putting this in the right place (this area is a stretch of my coding ability). The issue seems to be that after successfully completing step 1 (logging into the unity player account), the PlayerAccountService.Instance.IdToken is still null. So what I have now is:

Code (CSharp):

1.     async void signInWithUnity()
2.     {
3.         if (!PlayerAccountService.Instance.IsSignedIn)
4.         {
5.             try
6.             {
7.                 await PlayerAccountService.Instance.StartSignInAsync();
8.                 Debug.Log("Signed in " + AuthenticationService.Instance.PlayerId);
9.                 AuthenticationService.Instance.SignInWithUnityAsync(PlayerAccountService.Instance.IdToken);
10.             }
11.             catch (AuthenticationException ex)
12.             { Debug.LogException(ex); }
13.             catch (RequestFailedException ex)
14.             { Debug.LogException(ex); }
15.         }
16.     }

The debug is returning null and then I get this error: [Authentication]: Request failed: 400, {"title":"INVALID_PARAMETERS","detail":"external token not provided","details":[],"status":400}

 

Why are you providing the IdToken and not the AccessToken in

AuthenticationService.Instance.SignInWithUnityAsync(PlayerAccountService.Instance.IdToken)

?

 

You are correct, that was a typo. I corrected this but I'm still getting the same error.

Code (CSharp):

1.     async void signInWithUnity()
2.     {
3.         if (!PlayerAccountService.Instance.IsSignedIn)
4.         {
5.             try
6.             {
7.                 await PlayerAccountService.Instance.StartSignInAsync();
8.                 Debug.Log("Signed in " + AuthenticationService.Instance.PlayerId);
9.                 AuthenticationService.Instance.SignInWithUnityAsync(PlayerAccountService.Instance.AccessToken);
10.             }
11.             catch (AuthenticationException ex)
12.             { Debug.LogException(ex); }
13.             catch (RequestFailedException ex)
14.             { Debug.LogException(ex); }
15.         }
16.     }

I ran a debug after the StartSignInAsync() and it showed that the AccessToken was null

 

If you check his first post, then you see that he does so in the Start() method. I would also handle it differently and separate the different actions taken to not have sign in calls and validation in the same method.

 

Appreciate the continued assistance. As MiTschMR said, I am calling that exact code in my start function, which seems to be how the documentation suggests. If it should be in the actual sign in function I can certainly move it but some quick testing seems to run into the same error either way.

 

Ok, I've done that. See updated code below.

Code (CSharp):

1.     private async void Start()
2.     {
3.         await UnityServices.InitializeAsync();
4.         signInWithUnity();
5.         PlayerAccountService.Instance.SignedIn += signInWithUnity;
6.     }
7.  
8.     async void signInWithUnity()
9.     {
10.             try
11.             {
12.                 await PlayerAccountService.Instance.StartSignInAsync();
13.                 Debug.Log("Signed in " + AuthenticationService.Instance.PlayerId);
14.             AuthenticationService.Instance.SignInWithUnityAsync(PlayerAccountService.Instance.AccessToken);
15.             }
16.             catch (AuthenticationException ex)
17.             { Debug.LogException(ex); }
18.             catch (RequestFailedException ex)
19.             { Debug.LogException(ex); }
20.     }

Unfortunately I'm still getting the same authentication request failed error. I'm additionally getting a PlayerAccountsException because it's trying to login twice now, which is why I had put the !isSignedIn check in initially.

 

saadk_unity, this worked! Thank you so much. I don't know that I'd have ever been able to solve it otherwise.
