Ketting modded problem

Hiya, I recently set up a pc for hosting a small family modded server and currently am in the process of handling all the other stuff with it.

https://github.com/itzg/docker-minecraft-server Im using this for a docker image on it, and im trying to run Ketting on it, but I get this error on server startup

[12:17:45] [main/WARN] [ne.mi.ja.se.JarSelector/]: Attempted to select a dependency jar for JarJar which was passed in as source: curios. Using Mod File: /data/mods/curios-forge-5.14.1+1.20.1.jar

I understand that its some sort of a double dependancy from curios and cataclysm issue, but got really no idea on how to solve it.

Any and all help is welcome.
