Docker unable to download mods #4317

I'm trying to migrate my world over to a PC I just got for the sole purpose of hosting a server. When running the program, it seems to encounter an error when it comes to downloading the mods, saying that no files are available when I know they are. I've even manually installed them in the /mods folder without any luck. Any help would be much appreciated!!

.yml file:

services:
  mc:
    container_name: minecraft-server
    image: itzg/minecraft-server
    tty: true
    stdin_open: true
    ports:
      - "25565:25565"
    environment:
      MEMORY: 8G
      UID: 0
      GID: 0
      EULA: "TRUE"
      TYPE: FORGE
      VERSION: 26.2
      MODRINTH_PROJECTS: "@/modrinth-mods.txt"

    volumes:
      # attach the relative directory 'data' to the container's /data path
      - ./data:data

    restart: on-failure:3

It's telling you the problem...apparently more cryptic to be helpful:

ERROR : Invalid parameter provided for 'modrinth' command: No candidate versions of 'Trade Cycling' [fabric-1.0.22+26.2=beta, fabric-1.0.21+26.2=beta] matched versionType=VersionTypePref(versionType=release, prefersBest=false)

It's only finding beta versions and you haven't told it to allow beta versions. Just the default of release versions.

The "B" on the left means "beta".

I spot checked the first one in the logs and it seems like you meant to pick TYPE: NEOFORGE since Forge isn't a listed platform

Unrelated to the mods, but I noticed the volume mount is slightly wrong. The right side of colon needs to be /data and not just data

Thanks for the help!!

I double checked my Modrinth instance and it looks like I should have made TYPE: FABRIC so I changed that and added the missing / to /data

I also figured out that it didnt like me listing the mods in a text file so I've just added the list below MODRINTH_PROJECTS which seems to have fixed it for some of the mods as they'll download and add themselves to the mod folder, however others are throwing the error shown below (which will change if I rerun the container so it's not just one mod). It's not that there's not a version compatible with 26.2 because they all are compatible, but I'm not sure why they're reading as not having one.
