Help with Nextcloud docker installation with NFS hosted data directory

I have a TrueNAS server running with a storage pool & NFS share. In
the AccessControlList of the storage pool, the user is set as \`www-
data\` & group of \`www-data\` (See attached image). This is a user &
a group I have manually created in TrueNAS with a UID & GID of 33.
This is to match with the inner user within the Nextcloud docker
container that accesses this data.

I then have the Nextcloud docker container running on a separate
machine with the NFS share mounted as a volume inside the container at
\`/media/carrotmanmatt\_nas\_files\`. The data directory for Nextcloud
is then set to this path, so that theoretically my Nextcloud files
will be streamed over from the NAS while the local config files are
stored in a separate volume stored on the docker host (See \`docker-
compose.yaml\`). I have then run \`docker exec --user root
nextcloudapp chmod -R 755 /media/carrotmanmatt\_nas\_files\` &
\`docker exec --user root nextcloudapp chown -R www-data:www-data
/media/carrotmanmatt\_nas\_files\` to ensure all files are owned by
the nextcloud user.

To be clear I run the Nextcloud Docker container on a seperate host
from the NAS using Portainer.

When I then run the Nextcloud container, I can successfully create the
first admin user, but then when trying to access the main dashboard it
just shows this error:
\`\`\`
Internal Server Error
The server encountered an internal error and was unable to complete
your request.
Please contact the server administrator if this error reappears
multiple times, please include the technical details below in your
report.
More details can be found in the server log.

The log file could not be attached here, so are available here:

I think your doing too much with the --user flag. let the docker
container set the permissions on its own.
