Docker compose throws "invalid mount config" error

[Darkened6012]

I've got an issue setting up a Jellyfin container. I am using a mounted SMB share located at /media/media, when running docker compose it tells me:

Code:

Error response from daemon: invalid mount config for type "bind": bind source path does not exist: /media/media

Permissions for the folder are set to 755.

I've looked around online, and have found adjacent issues, but not specifically this error for an SMB share. I'm sure it's something simple that I don't know. I attached my compose file for reference. The SMB share is accessible if you access the folder manually, and media can be viewed. 

I did put this up on Element, but that format is just bad for getting help when I can't sit there and stare at it hoping I get a reply.

If the mount is present on the host, docker will find it. This is not a Jellyfin issue per se, but we can probably help. What do you get when you ls /media/media?

This is kind of what I thought, so I'm not sure what the hangup is. I definitely appreciate the help as I'm still learning Docker and my Linux skills are not particularly refined. 

When I ls /media/media I get a list of folders from the server that the SMB share is linked to.
