Initializing Unity IAP when having UDP store active after updating from Unity IAP 1.22 to 1.23.1

After updating Unity IAP from 1.22 to 1.23.1 the Unity IAP initialization will throw an exception when having UDP store selected. We also updated to using In App Purchasing package 2.0.6.

Code (CSharp):

1. InvalidOperationException: StoreService cannot find valid GameSettings.asset file! Initialization failed!
2.   at UnityEngine.UDP.StoreService.Initialize (UnityEngine.UDP.IInitListener listener, UnityEngine.UDP.AppInfo appInfo) [0x00000] in <00000000000000000000000000000000>:0

 

Are you trying to publish to UDP? Are you following the directions here? https://docs.unity3d.com/Packages/com.unity.purchasing.udp@1.3/manual/index.html

 

Yes, we are publishing to UDP, we have that target selected from Window -> Unity IAP -> Android -> UDP. Then on runtime we use Unity IAP and call

UnityPurchasing.Initialize(IStoreListener, ConfigurationBuilder)

and that causes this exception. With Unity IAP 1.22 this worked without an issue and I also think we tested this on 1.23 and it worked, but cannot reproduce as 1.23 is not downloadable anymore.

 

@JeffDUnity3D any extra information on this case?

 

Thank you for the response. It looks like the updating process removed the UDP Settings.asset file. Restoring it fixed the issue.
