[7.0 RC1] - Tailscale Container Integration Permission Denied Issue

I tested the new Tailscale integration with containers.
It worked fine for the Immich container, but I encountered an issue with All-The-Mods-9 (goobaroo/allthemods9:latest) :

=======================

Executing Unraid Docker Hook for Tailscale

Detecting Package Manager...
Detected Advanced Package Tool!
Tailscale Troubleshooting enabled!
Installing additional packages: curl, dnsutils, iputils-ping, speedtest-cli

Please wait...

ERROR: Unraid Docker Hook script throw an error!

=======================

Is this issue related to the container itself or the Unraid Docker Hook for Tailscale?
