Current behavior

When a response generated by a worker is too big, a log is displayed indicating that the worker has finished the processing and returned the result but the client never receives it.

Expected behavior

If the response is too big, either an error message should be received by the client or the worker should fail and should be able to catch the error to handle it.

Minimal reproduction of the problem with instructions

1. Create a new project
2. In the worker code, do a loop to generate a string with 1000000 concatenated 'hello'
3. Run both worker and client
4. Client calls the worker
   => no answer and no error at all

What is the motivation / use case for changing the behavior?
