Nextcloud doesn't deploy if you follow the TrueNAS scale instructions due to postgres ownership

Hello,
I am stuck with the same problem.
To be complete, I was stuck in maintenance problem, but I erased the app, and reinstalled it. So I am free from the maintenance problem but I am now stuck in deployment.
I checked the owner of the different datasets I am using for Nextcloud and if I try to save the ACL for the PostGres data and backup, I got

[EPERM] Filesystem permissions on path /mnt/JenniFonZ/AppData prevent access for user “netdata” to the path /mnt/JenniFonZ/AppData/NextCloud/pgdata. This may be fixed by granting the aforementioned user execute permissions on the path: /mnt/JenniFonZ/AppData.

The Owner are already user “netdata” and group “docker” for the data, but not for the backup.
Do you know how I can fix this?
Thank you!
