Nextcloud version: Nextcloud Hub 8(29.0.7)

This isn't a supported version of Nextcloud Server. v29 has reached end of life. Additionally, you're behind multiple maintenance (bug fixes) releases even just for v29.

If you have access to your command line run e.g.: sudo -u www-data php occ config:list system from within your Nextcloud installation folder

You also left your config completely blank so not sure we can do much here.

Your report is appreciated but it's not happening in any environment I have access to. I suspect this is something either due to the outdated version or some other element of your environment which I can only guess at since there's no configuration.

Please update to the latest maintenance version of any supported major release (v30 or v31). Feel free to edit your Issue to include your configuration as well.

There is no code in the notes app that could trigger this as far as I'm aware. Could also have been the background job and may depend on the user backend. Is this always reproducible for you?

Are you sure this log entry is from Notes v4.12.1? It looks more like v4.12.0.

Morning, many thanks for the quick respond. We have the same issue when we used other Nextcloud settings, so it's not problem of Notes, so apologizes for false issue.
We will upgrade the Nextcloud.
Best regards!
