Jupyterhub + DockerSpawner: Error in Authenticator.pre_spawn_start: APIError 400 Client Error: Bad Request (“invalid tag format”)

问题

I'm loading jupyterhub within an iframe. Both the parent page and jupyterhub use the same authentication service(keycloak). I first login with my username(rabraham) to my parent page and then I open an iframe and start jupyterhub and I logon to jupyterhub. It logs on just fine but fails at the next step giving perhaps when using DockerSpawner

500 : Internal Server Error
Error in Authenticator.pre_spawn_start: APIError 400 Client Error: Bad Request ("invalid tag format")

You can try restarting your server from the home page.

Here are my logs if that helps:

回答1:

The error comes from your local docker repository. So you probably should check the logs of the private docker repo on localhost:5000.
