Matcher stuck in reboot loop

[dunwiddie]

I've got everything set up and working, except that Matcher is constantly restarting. I've got everything else running in Docker. The only modifications I made to the example Docker compose file was adding existing networks (with Traefik) so I can eventually connect Meelo's services up to other parts of my Docker network.

My immediate guess is that this is a permissions/privilege issue based on CRITICAL:root:{'enabled': ['Unknown field.']}, but I don't know where to start. Happy to provide additional information as needed.

Hi @dunwiddie! Could you provide the content of the settings.json file (obfuscating any sensitive information) please

Hi! Thanks, yeah the enabled field in the providers object is not needed anymore (it's been deleted a while ago). You'll have to remove the "enabled": ..., lines.

To disable Discogs as a provider, you'll have to remove the discogs entry.

Also, I think the API key field should be apiKey and not apikey.

Let me know if that worked :)

[Arthi-chaud]

Hi @dunwiddie did you manage to make it work?

[dunwiddie]

Yes! I believe it was leaving the Discogs provider in the file when it was disabled that was causing the issue.
