DJIV5/RXUtil error causes app to crash shortly after application start and successful app registration

[danekpilar01]

Hello, I started with an empty project and implemented the basic steps for using the SDK.

My app only uses a single Activity, where it initialises the SDK, checks for permissions, registers the App with the API key and in case when product is connected, a simple textview displays a message that the product is connected.

The registration goes well, but after one or two seconds, an exception is thrown and the app crashes, but I don't get any useful information from the error message:

(co_a:34) io.reactivex.rxjava3.exceptions.OnErrorNotImplementedException: The exception was not handled due to missing onError handler in the subscribe() method call.

If you are not currently using the latest 5.8 version, could you please update to version 5.8 before conducting the test? I did not find any information in the logs you provided regarding the location of the crash.

Thank you.
