500 Error when starting Notebook

[rwmajor2]

I have followed the instructions to get setup with JupyterHub and the GitHub Authenticator. However, I am using my own Docker image, built from jupyter/base-notebook. Once I log in and authenticate, I get the following message:

500 : Internal Server Error
Redirect loop detected. Notebook has jupyterhub version unknown (likely < 0.8), but the Hub expects 0.8.0. Try installing jupyterhub==0.8.0 in the user environment if you continue to have problems.
You can try restarting your server from the home page.

What does this mean exactly? Is this error coming from my individual notebook server?

Looking at @minrk comments on jupyterhub/jupyterhub#709 I suspect your singleuser notebook image does not have a matching version of Jupyterhub.

If you set DOCKER_NOTEBOOK_IMAGE in the .env file and then do make notebook_image it should take care of it for you. Did you directly edit jupyterhub_config.py?

@dalg24 Thanks. I was using my own image and it was slightly older and had jupyterhub 0.7 installed. I updated and it worked. Thanks!
