Does anybody else have this problem after updating to the latest docker image?
How to debug it?

Thank you very much!

I am having the same issue, but one step later.
It stucks and shows a white page after hitting the Import-button.

The log looks the same as yours.

I have set up a new docker container using the docker image and created a new configuration as well. Since then it works for me. Nevertheless I would be happy to get an idea how to debug problems in future to be able to report or help to fix problems. @dklinger is your problem still there?

Yes, this is a good point. The whole import is not well guarded against an incorrect (aka old) config.json. This could be addressed e.g. with a simple json schema checking.
