Error 500 on trying to access change-password page #691

Closed mangecoeur closed 3 years ago

Bug description

I'm testing out TLJH in a VM, installed with only default options. I added a user, then tried changing the user password at /hub/auth/change-password . I get a 500 internal server error

Expected behaviour

Reach the password change page

Actual behaviour

Logs (journalctl) show this error:

I opened a similar bug within the First Use Authenticator: https://github.com/jupyterhub/firstuseauthenticator/issues/36

@swill thanks for a very thoroughly documented issue and tracking this down so clearly! This has been resolved in firstuseauthenticator. A release should be made and we should upgrade that package in TLJH. This is now represented by #738.
