Sonarr reports that a directory doesn't exist, while it exists... Please help...

I get this error message:

You are using docker;
download client SABnzbd places downloads in /pool/media/usenet/complete/tv
but this directory does not appear to exist inside the container.  Review your remote path mappings and container volume settings.

But it does exist, and it does have access to it. I’m losing my mind over this.
This is my compose config:

homeserver@homeserver:/app$ docker compose config sonarr
services:
  sonarr:
    container_name: sonarr
    depends_on:
      prowlarr:

        target: /pool/media
        bind:
          create_host_path: true
...

This is the users/groups on the host:

root@homeserver:/pool/media/usenet/complete/tv# id sabnzbd
uid=3026(sabnzbd) gid=2003(usenet) groups=2003(usenet)
root@homeserver:/pool/media/usenet/complete/tv# id sonarr
uid=3028(sonarr) gid=2002(media) groups=2002(media),2003(usenet)

This is proof that the directory (/pool/media/usenet/complete/tv) exists on the host:

root@homeserver:/pool# cd media/
root@homeserver:/pool/media# cd usenet/
root@homeserver:/pool/media/usenet# cd complete/                 
root@homeserver:/pool/media/usenet/complete# cd tv/
root@homeserver:/pool/media/usenet/complete/tv# ls -la
total 33
drwxrwx--- 2 sabnzbd usenet 2 Oct 20 18:32 .
drwxrwx--- 9 sabnzbd usenet 9 Oct 20 18:38 ..

This is proof that the directory exists inside sonarr’s container:

homeserver@homeserver:/app$ docker compose exec sonarr sh
root@9259da4cbbd7:/# id
uid=0(root) gid=0(root) groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel),11(floppy),20(dialout),26(tape),27(video),2002(abc),2003
root@9259da4cbbd7:/# cd /pool/media/usenet/complete/tv
root@9259da4cbbd7:/pool/media/usenet/complete/tv# ls -la
total 33
drwxrwx--- 2 3026 2003 2 Oct 20 18:32 .
drwxrwx--- 9 3026 2003 9 Oct 20 18:38 ..

This is proof that the directory exists inside the container from sonarr’s user’s perspective:

homeserver@homeserver:/app$ docker compose exec -u 3028  sonarr sh
abc@9259da4cbbd7:/$ id
uid=3028(abc) gid=2002(abc) groups=2002(abc),1000(users),2003
abc@9259da4cbbd7:/$ cd /pool/media/usenet/complete/tv/
abc@9259da4cbbd7:/pool/media/usenet/complete/tv$ ls -la
total 326
drwxrwx--- 12 3026 2003 12 Oct 20 18:57 .
drwxrwx---  9 3026 2003  9 Oct 20 18:38 ..

What am I missing?!? This issue is starting to take its toll on me, haha…

The only thing I can think of is maybe you have a “Remote Path Mapping” configured under “Settings/Download Clients” and it is confusing things. Since Sonarr can get to the directory directly where SabNZBd is putting downloads, Remote Path Mapping is not needed.
