An abundance of JSONDecodeError

[yyolk]

While using the JsonRPCClient; the oracle will see an abundance of JSONDecodeErrors that are coming as a result of the server saying it's too busy.

I was aware of this happening, and was swallowing, notifying and then raising FailedExecutionWillRetry

Got a JSONDecodeError of 'Expecting value: line 1 column 1 (char 0)'. Retrying the transaction by failing this execution.

JSONDecodeError: Expecting value: line 1 column 1 (char 0)
