So what you're seeing is this error: https://stackoverflow.com/questions/71314384/docker-var-lib-docker-overlay2-id-merged-no-such-file-or-directory . I've seen it before occasionally too with other addons.

I don't really have a sense of why it happens sometimes but when it happens the fix is pretty straightforward. First try running ha su repair from the cli and then starting it again. That should clean up images and containers and try to fix it.

If it still won't start then reboot the host. That is the HAOS equivalent of restarting docker from that post I linked (since everything in HAOS is in docker containers). That has always fixed the issue for me.

Thanks for trying to help out @mdegat01 . Since I made the report i created a working workaround. It turns out the complete Z-wave network works just fine without zwave JS and only zwave js2mqtt. This has worked great form me. On the other hand this whole 500 server error left me a bit worried. If this tends to happen to add-ons, what's the chance of it happening again to another add-on and how to fix it then.

I'm gonna close the issue for now (close as not planned/reproduces/stale) and hope that whenever this happens again someone can reopen the issue and make not of it happening again. If enough people get this issue, a solution should then be make/found/created...
