Incomplete async stack traces

[mihai1voicescu]

Motivation

Some errors have their stack traces incomplete, making them impossible to debug. Example:

 02-01 17:42:09.667  E  [6652/6652] AndroidRuntime FATAL EXCEPTION: main
 02-01 17:42:09.667  E  [6652/6652] AndroidRuntime Process: io.almer.remoteassistence, PID: 6652

This looks like an internal error and I have nothing to debug it with or no additional info...

Even wrapping all the requests in try catch does not help in catching this...

Desired solution

Having the actual call site would be great. Also being able to catch the errors seems necessary.

Hey, if I understand correctly you stacktrace, there is an error with type io.rsocket.kotlin.RSocketError$ApplicationError thrown, and you catch it, right? Such an error says that on responder side (f.e. server) something failed and responder has sent Error frame. On current moment, there is only message of Throwable is transmitted via network.

Do you have access to responder side of code? Does it have full stacktrace there? Or may be you can tell me, in which situation (code reproducer) this happens?
