I had an image of Nextcloud v. 14 in my production environment (AWS ECS).
On September 22, the service stopped because the volume was full.
Expanding the CPU, the error that appears to me is:
The "maintenance: install" command is not defined.
I have not made any modifications in to the cluster. This error started when the CPU reached the limit. I tried to update the version, but the error is the same. I still haven't found the solution.
