Well increase your log_level to 1 or something, when you don't want to see debug messages in your log.

[koreywithak]

@nickvergessen Regardless of what log level this is set as, it sounds like something that shouldn't be happening (probably should be "info", "warning" or "error"). I don't recall seeing it before upgrading to NC11. Increasing the log level will just hide the issue. I'd prefer a good (less snide) explanation of why it is acceptable for the default cron job to not be able to locate a path.

[nickvergessen]

Can you provide a backup of your jobs database table?

[koreywithak]

I know where most logs are and how to get to the mariadb table, but I don't know what the jobs database table is...

[nickvergessen]

in mariadb in your database nextcloud there should a table named oc_jobs

I'm seeing this very message on the v18 branch and wonder what the fix is - and why this ticket was closed without any reason / solution stated.
