Using dummy authentication, the logged in user cannot exit

Hi
My environment is jupyterhub + k8s + jupyterlab, and the authentication uses dummy.

I can start and log in normally, but I can’t log out.

Configuration for authentication:

c.JupyterHub.authenticator_class = 'dummy'
c.Authenticator.admin_users = {'root'}
c.Authenticator.allowed_users = {'root','limy'}

log information of logout:

Add self-test information:

When the logout invalid configurable-http-proxy is 0.2.1 version, and use pip to install.

I uninstall the PIP installation package, and use the NPM installation to log out.

The reason why I use pip to install configurable-http-proxy is that I need to rewrite the authenticator and run the jupyterhub project in pycharm, but the pycharm package cannot find configurable-http-proxy when running the project.

Is there a better way to handle the exception that configurable-http-proxy cannot be found when pycharm runs the jupyterhub project?

The Python implementation of configurable-http-proxy is separate from the official NPM, so there may be differences. If you have problems it’s best to test with the NPM version.

I’ve never used pycharm, but my guess is it’s not using the correct path to find the required executables.

Thanks !

I now use NPM’s configurable HTTP proxy for testing and can log out normally
