Subscriptions stopped working with 1.22.0

Hi, we recently updated our Unity IAP to version 1.22.0 and suddenly got a lot of errors from our users concerning Google Play subscriptions.

Code (Error):

1. KeyNotFoundException: The given key was not present in the dictionary. System.Collections.Generic.Dictionary`2[System.String,System.Object].get_Item (System.String key) UnityEngine.Purchasing.SubscriptionManager.getGooglePlayStoreSubInfo (System.String payload) UnityEngine.Purchasing.SubscriptionManager.getSubscriptionInfo ()

We also sometimes get this Play Store error when trying to purchase the same subscription: DF-DFERH-01.

It seems to only happen to users who were already subscribed prior to the update. Purchasing the subscription as a fresh user works just fine.

Anyone got any tips?

 

A subscription is a non-consumable and should only be able to be purchased once.

 

Still doesn't explain why our users suddenly "lost" their subscriptions when we updated.
And prior to the update, you were able to click our in-game purchase button to receive a Play Store popup basically saying "You have already bought this" instead of getting a "Error while retrieving from server".

So, obviously something changed with the 1.22.0 update.

 

What do you mean, lost their subscriptions? Do you mean that ProcessPurchase is not called upon reinstall for this product?

 

No, your internal IAP code can't seem to find the info about the subscription when we have initialized it.
To activate the subscription effect in our game we check on startup if the subscription is still active and then we get the error mentioned above to our GameAnalytics dashboard.

This error.

Code (CSharp):

1. KeyNotFoundException: The given key was not present in the dictionary. System.Collections.Generic.Dictionary`2[System.String,System.Object].get_Item (System.String key) UnityEngine.Purchasing.SubscriptionManager.getGooglePlayStoreSubInfo (System.String payload) UnityEngine.Purchasing.SubscriptionManager.getSubscriptionInfo ()

Basically, it fails to retrieve SubInfo for players who already have active subscriptions.

 

@CaelumNoctis Please show the code that you are using to check if the subscription is still active.

 

This is what we do on startup. Hope it's readable.

Code (CSharp):

1. public void OnInitialized(IStoreController controller, IExtensionProvider extensions) {

4.             Player.instance.subscriptions.RemoveAllSubscriptions();

Understood, you are explicitly calling getSubscriptionInfo which seems to be throwing the exception, can you confirm this single call causes the issue?

 

Yes, the only errors we've seen are from this single method

 

We'll try downgrading Unity IAP to what we had before and see if that helps.

 

@JeffDUnity3D I'm currently having the same problem, would like to see some kind of answer for this

 

Testing with a previous version would be a reasonable approach until we are able to get to this here.

 

So we tried doing a rollback to IAP version 1.19 and the KeyNotFoundException error seems to have decreased. It's still there though. And when I check our GameAnalytics logs our errors seems to have started before we updated our IAP version. So maybe something on Google's side happened that you don't support?

Just to clarify, the problems are only for the Google Play Store

 

Sorry, decreased? So it works OK in your testing sometimes, and other times it does not?

 

In our testing we never have any issues on our own devices. The errors have decreased overall based on error logs from all of our players

 

@JeffDUnity3D To clarify, we have never gotten this error ourselves, we've only seen it in error logs on our GameAnalytics dashboard

 

I used to have the same issue and eventually I managed to fix it:

IN A NUTSHELL: check if your product type matches between the one configured in the app catalog with the one configured in the store.

I don't know if this is your cases, but maybe you can double check it.

In my case, I imported the product catalog from a CSV. Unfortunately, I had a subscription that was imported as a non consumable product. I kept that product in the store catalog but I changed the type in my local catalog, and I added a new subscription for testing. Then the error appeared, until I changed the type of the local product to non consumable.

 

@LuisJavierLopez This is sadly not our issue since we manually add our subscription SKUs to the ConfigurationBuilder seperately

 

Hi,

We just updated from Unity purchasing 1.19.0 to 1.22.0 and released to Google Play and ran into the same issue when going live :

```
Unity : Name: KeyNotFoundException: The given key was not present in the dictionary.
Unity : Message: Exception
Unity : StackTrace: System.Collections.Generic.Dictionary`2[TKey,TValue].get_Item (.TKey key)
Unity : UnityEngine.Purchasing.SubscriptionManager.getGooglePlayStoreSubInfo (System.String payloa
Unity : UnityEngine.Purchasing.SubscriptionManager.getSubscriptionInfo ()
```

We have not changed anything related to getting the subscription information (we updated to get access to intro pricing support on GooglePlay). We were not able to see this issue before release in our sandbox subscription tests. This issue appeared when our version went live and we are now rolling back to 1.19.0 hoping it will fix the problem. We managed to reproduce with one of our devices on the live version but are unable to get more information on what exact steps are involved in the reproduction of the issue. It seems to affect a large majority of our existing customers with a subscription.

Did you have any chance to look into this issue?

 

@mradel Can you clarify, is this occurring in your Alpha/Beta testing too?

 

This was occurring in our live version, affecting a very large portion of our customers. We just released a version rolling back to the IAP plugin 1.19.0 and while this have solved our issue, there are features we cannot access anymore (intro pricing).

As far as I know we have not seen it in Alpha/Beta testing, we did not use the beta testing track for the first update where we had the issue or for the patch rolling back to the previous version as we only saw it live, we assumed any kind of sandbox testing could also produce false positives.

Here is what we are trying to do on GooglePlay :

Code (CSharp):

1. var subscriptionManager = new SubscriptionManager(receipt, productId, null);
2. var subscriptionInfo = subscriptionManager.getSubscriptionInfo(); //This call results in the issue

 

I will be testing this today and will report my findings

 

I am not able to reproduce. Before submitting to the IAP team, I need to reproduce first. I'm using IAP 1.22 and Unity 2019.1.4f1 and the Sample IAP project here, using the code from IAPDemo.cs. I'm on a device with US locale. https://forum.unity.com/threads/sample-iap-project.529555/

This is my code:

Code (CSharp):

1. public void OnInitialized(IStoreController controller, IExtensionProvider extensions)
2.     {
3.         m_StoreController = controller;
4.         m_StoreExtensionProvider = extensions;
5.  
6.         m_AppleExtensions = extensions.GetExtension<IAppleExtensions>();
7.         Dictionary<string, string> introductory_info_dict = m_AppleExtensions.GetIntroductoryPriceDictionary();
8.        
9.         foreach (var item in controller.products.all)
10.         {
11.             if (item.availableToPurchase)
12.             {
13.                 if (item.receipt != null)
14.                 {
15.                     if (item.definition.type == ProductType.Subscription)
16.                     {
17.                         string intro_json = (introductory_info_dict == null || !introductory_info_dict.ContainsKey(item.definition.storeSpecificId)) ? null : introductory_info_dict[item.definition.storeSpecificId];
18.                         SubscriptionManager p = new SubscriptionManager(item, intro_json);
19.                         SubscriptionInfo info = p.getSubscriptionInfo();
20.                         MyDebug("Called sub info for " + info.getProductId().ToString());
21.                     }
22.                 }
23.             }
24.         }
25.  
26.         MyDebug("OnInitialized: PASS");
27.  
28.     }
