Using 2.1.0 here.
I could not even catch the exception with websocket_exception nor "..."
When the receive is ongoing and the close is called, the rest sdk internal code crashes without any chance to catch the exception.

Stack trace of the error:

Suggestions?
Comments: Hi raffaeler, I tried taking a look at this but didn't notice any issues. The code you've provided uses lots of variables and calls other functions that we can't see here. Is it possible you could provide a standalone repro of the problem? Or at least all the complete code with instructions on how to use? Without any more information I'm likely going to have to close this. Thanks, Steve
