[BUG] First run with empty /config, unable to login/register

[mcinj]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

On first run of this image I see errors in the logs. The webui loads on the exported port with a login screen, but no way to register. I'm not aware of default credentials.

Expected Behavior

I should be able to register or login on first run.
