Client-only mods not being properly excluded

[danialborta]

Using AUTO_CURSEFORGE with a local modpack.zip didn't work so switched to using a curseforge-generated manifest.json. The modpack is custom, so it includes client mods, but I was under the impression that the automatic filtering would filter the client mods out. Tried manually excluding some, but the server still tries to load them (e.g. Oculus, which you can see in the error message below.

What am I doing wrong?

Compose:

services:
  minecraft:
    image: itzg/minecraft-server
    volumes:
      - minecraftdata:/data
      - /home/Minecraft/manifests:/manifests:ro

        oculus
        journeymap-integration
    restart: unless-stopped
volumes:
  minecraftdata:

The server will also fail to start and then auto-restart and loop forever. I'm only pasting one loop in for brevity.

Section that makes me believe it's loading client-side mods and crashing:

I restorted to using the manifest.json because the zip file method with "TYPE: FORGE" wasn't working, and I'm not publishing this modpack. If I need to manually remove client-side mods from the json let me know but seems tedious.

Cheers for any help!

I just tried deleting the manifest.json entry for oculus (ID: 581495), and gave the compose.yml the lines

CF_FORGE_REINSTALL_MODLOADER: true
CF_FORGE_SYNCHRONIZE: true
REMOVE_OLD_MODS: TRUE

But the error persists, still says 'oculus has failed to load correctly'

UPDATE:

I decided to give up on auto_cf and now I just uploaded a .zip of all my jar files into the mods folder of the server, then used a

TYPE: FORGE | MODPACK: 'modpacks/pack.zip'

configuration. The server will launch with seemingly only a few warnings, it will copy the mods from the .zip into the mods folder, but when I boot up the client side through CurseForge and then try to join the server, minecraft cancels the connection and tells me that like 25 of the mods are on my client but not on the server. I've checked the /_data/ file in my docker volume and can see all the jar files I expect, but it just seems to not be loading them into the server???

CF_FORGE_SYNCHRONIZE is misspelled, should be CF_FORCE_INCLUDE_MODS as in "force" with a "c".

Also I'll look into adding more info to the docs about how the client-only determination is processed.

Ok I have no idea what was corrupted or what but I deleted my old volumes and directories, recreated everything from scratch with the configuration file below and it was fixed.
