LMS restarting with DB access error?

[citymonitor]

Hi there,

I'm trying to migrate a running version of this docker container to a new one. Therefore I copied the contents of the old mounted volume /srv/squeezebox to the local dir and start the container (compose-file).

However, it keeps restarting with the following error:

Any idea what's wrong here?
