As described in #730, it seems ConnectionFileMixin is expecting
ports
to be List[int].https://github.com/jupyter/jupyter_client/blob/5742d84ca2162e21179d82e8b36e10baf0f8d978/jupyter_client/connect.py#L386
IPKernelApp is overriding such attribute and changing its type, which generates the error described.
This is the simplest fix I could come up with. Since I am not familiar with the project, please take this as a suggestion.
