I was getting this issue too - see discussion on #65

It seems to be a problem with updates to jupyter_client and possibly notebook as well, when using the NotebookApp backend. Pinning the following should fix it:

jupyter_client<8.0.0
notebook<=6.4.11

Once the next release of appmode occurs then the ServerApp backend will work with Appmode and you can just use that instead, which doesn't have the same error messages when using the latest version of jupyter_client.

FYI there are underlying issues in zmq / tornado as you can see here jupyter/notebook#6721 that might cause some confusion because it generates a very similar stack trace as above.

For people reading this because they found this issue through search, please check jupyter/notebook#6721 first 🙏🏻 - I would guess that this appmode extension is not the cause of your issue.

It seems this is not actually an issue with Appmode.
