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, Can you provide the websocket client code you have? Thanks, Steve
