Following the Tailscale instructions from SpaceInvaderOne I wanted to get the Flame dashboard working as its own separate Tailscale device so that I could reference in the browser using magicDNS. My first issue occurred but was solved here:
Unraid 7 / Add Container / ERROR: Couldn't detect persistent Docker directory for .tailscale_state! - Tailscale - Unraid

Per the instructions, I did something like:

because my directory is:

The container starts, but it fails soon after despite looking ok in the logs initially. Digging deeper into the logs, I see the following:

Executing Unraid Docker Hook for Tailscale

Tailscale found, continuing...

Usage: chown [-RhLHPcvf]... USER[:[GRP]] FILE...

-h Affect symlinks instead of symlink targets

-L Traverse all symlinks to directories

-H Traverse symlinks on command line only

-P Don't traverse symlinks (default)

-R Recurse

-c List changed files

-v Verbose

-f Hide errors

root@MediaServer:~#

Anyone know why this may be occurred or if I have set something incorrectly?

Maybe to give more information,

• The container works fine without Tailscale integration. Something in the docker run with tailscale is causing an issue.

• I think something is wrong with the 3 lines of the docker run:

-e ORG_CMD="sh

-c chown

-R node /app/data && node server.js"

These should be one line right? Can I fix this or am I incorrect about this is the issue?
