I am calling self.emit on reconnect event but it causes the program to crash. Why? How do I implement proper reconnect to source

Note there were several hours between connect and reconnect, it's not clear in these logs

Are you running the client against a load-balanced server?

You can activate logging with the following commands.

import logging
logging.basicConfig(level=logging.DEBUG)

Please feel free to reopen this issue if the above fix does not work.
