ValueError: No JSON object could be decoded

Start in wxbot.py at send_msg_by_uid on line 792 and trace the response from the message-handling path shown in the traceback. Reproduce the failure with the reported message and inspect why the response cannot be decoded as JSON. Done means this scenario no longer raises ValueError during message processing.
