How do I resolve this version error?

[Rubyzillaaa]

These are the docker logs I get when trying to run a cobblemon server, I am super inexperienced so if it's a simple answer I missed I apologize

Why are you listing hundreds of files in CURSEFORGE_FILES in addition to the hundreds of files that are already part of the modpack? I sure hope you weren't attempting to list the entire modpack content yourself 😬

Something you listed is a texture pack instead of a mod file. Looks like appleskin maybe.

[Rubyzillaaa]

Hahaha sorry I'm super out of my depth here, is there an easy way to just link the custom mod pack my friend made in curseforge? I'm using setupmc, I made one server a long time ago doing it this way so I must have gotten very lucky lmao, also thank you I will remove that!
