Borg.config file was deleted from mastercontainer?

when I attempt to create a backup in the AIO :8080/containers I get the following error in the log:

Performing backup…
Did not find borg.config file in the mastercontainer volume.
Cannot create a backup as this is wrong.
chmod: /nextcloud_aio_volumes/nextcloud_aio_nextcloud_data/skip.update: Operation not permitted

from my docker host here is what I see in the borg.config directory:

root@app03:~# nano /var/lib/docker/volumes/nextcloud_aio_mastercontainer/_data/data/borg.config
root@app03:~# nano /var/lib/docker/volumes/nextcloud_aio_mastercontainer/_data/data/           
backup_archives.list  backupsecret          configuration.json    session_date_file     
root@app03:~# nano /var/lib/docker/volumes/nextcloud_aio_mastercontainer/_data/data/

I got this error and executed the recommendation, thats how this started:

“No borg config file was found in the targeted directory.”
“This might happen if the targeted directory is located on an external drive and the drive not connected anymore. You should check this.”
“If you instead want to initialize a new backup repository, you may delete the ‘borg.config’ file that is stored in the mastercontainer volume manually, which will allow you to initialize a new borg repository in the chosen directory:”
“sudo docker exec nextcloud-aio-mastercontainer rm /mnt/docker-aio-config/data/borg.config”

I got it back using this solution I found:
