It seems AdMob is logging this error internally, so I can't get more details on this. Here is the logcat that AdMob logs:

I was unable to see this issue on 8.3.0 running on an Android 10 device. Can you provide any additional details?

[Nyankoo]

@NVentimiglia Sadly no, as the exception appears to be thrown inside of the AdMob SDK. I wrapped all calls in try-catch blocks but nothing is propagated upwards for taking a closer look.

I'm currently waiting on the next AdMob update, which hopefully fixes issues mentioned in other issue threads, so I'm unable to test with version 8.3.0.

[Nyankoo]

@NVentimiglia Quick question: does the DSGVO form on the AdMob dashboard needs to be published when the call is made? When I want to publish it in the dashboard, it notifies me that I need to add the SDK Code first before publishing. so it's still a draft.
Could this be the issue or should an app update with the SDK be published first before publishing the DSGVO form?

@Nyankoo

Yes you should Create GDPR messages for apps.

Considering how mysterious this issue is, I suggest you open a case on the support forum. Please include a minimal code sample, your app id, and a reference to this issue.

[Nyankoo]

@NVentimiglia Just tested it and yes, the GDPR form needs to be published on the AdMob dashboard, otherwise the exception is thrown.

I feel the documentation is a bit unclear on this and the exception not very helpful. Maybe the exception should give more feedback on this to help other developers running into this?

@Nyankoo

Correct, you will need to create and publish the GDPR message first.
