Hello @ntsparis!

It seems this issue is not Datadog SDK fault (Datadog SDK is in the exception stacktrace just because of the interceptor installed), but rather you should implement error handling in your Rx chain. For more information you may want to check the following links:

@0xnm i am not sure since we have implemented error handling all over the application and there is no crash until datadog sdk implementation. We use just (Deprecated) interceptor DatadogInterceptor() is this could be a problem?

[0xnm]

@ntsparis You have io.reactivex.exceptions.OnErrorNotImplementedException meaning some stream is missing the case for this error.

Using a deprecated constructor is not a problem.

It's true that this error seems related to an unhandled case, but in our project, we already use a base error-handling mechanism, so this issue should have appeared even before integrating the Datadog SDK. It's strange that the crash was triggered only after the SDK's installation and not before?

Additionally, I'd like to share another stack trace to highlight that the issue arises specifically due to the error, not the implementation structure. It's important to note that this error didn't exist prior to integrating Datadog, and both Crashlytics and Google Console are providing insights pointing directly to the specific SDK. We have also share crash from Google play console.
