Bug Multiple exceptions after updating to the v4.4.1

Hi,
we updated Unity IAP package to remove "Google Play Billing" warning in Google Play Console and now we're seeing many exceptions in Cloud Diagnostics. All exceptions mention "Unity.Services.Core".

Here are some of the stack traces:

and the last stack trace report is only single line, but it was reported more than 12000 times by only 3 impacted users:

Additional details:

• Unity version 2021.3.9f1
• IAP Package version 4.4.1
  
• Services Core version 1.4.3
  
• Remote Config version 3.1.3

Is this a known issue or it might be result of some implementation error? Inapp purchases seem to be working fine when we test the games, but we can't replicate these exceptions on our devices.

 

We are seeing this behaviour too.

• Unity version 2020.3.15f2
• IAP Package version 4.4.1
  
• Services Core version 1.4.0
• Analytics 4.0.1

Here's is a snippet of our packages-lock.json.

Code (json):

Please fix this!

 

I'm now realizing this might not be the same issue.
Please confirm, I'll open another thread

 

Thanks!

 

I am also facing similar exceptions in Unity Cloud Diagnostics.

• Unity version 2020.3.39f1
• IAP Package version 4.4.1
• Services Core version 1.4.0
• Analytics 4.0.1

Also there are several log messages with:

 

We are also seeing the exception that @Sailendu posted:

But we are not using Cloud Build.
We have only built on Android. No IOs yet.

 

Another Trace that might be related:

 

Very sorry, we couldn't repro it ourselves.
We are just getting it from GooglePlay Console and Crashlytics

If I find anything more, I'll update.

Thanks

 

I also can not reproduce it, the exceptions are appearing in Unity Cloud Diagnostics where the user crashes are viewed, I am also not using Cloud Build, it is on Android, have not uploaded the same build to iOS yet, so not sure about iOS.

 

We are also experiencing the same exception @Sailendu posted.
Unfortunately we can't reproduce it.

Any news on this issue?

 

Is Unity IAP not supported on ANY Xiaomi or Huawei devices? Or just on those of them which does not include google services?

 

My personal device is a Xiaomi with GPS installed and it works just fine, we have a few of huawei / xiaomi on the office, it works on all that have GPS installed, and does not on the ones that doesnt.
My estimated guess is that it works with GPS installed. But the officiall Unity stand is that it is not supported for that reason (or any other reason) to avoid troubles (which is fine).

I really wish that if: the device is not supported for IAPs (or the GPS are not installed), Unity would call "OnInitializedFailed" instead of sending us Non-Fatals on Crashlytics.

Just avoid using in-apps if GPS are not installed.

 

Hi! Are there any updates?

 

Did you mean December 12th?)
