Paper type not even considered

[CestQuoiUnPseudo]

Hey, I'm having a lot of fun with the container. Lots of configurations and very easy to setup!
That being said i'm having a bit of an issue switching to paper
I've tried changing the TYPE: ${TYPE} to TYPE: "PAPER" in the compose file, not defining PAPERBUILD to get the default, restarting the stack, restarting the container, re-pulling the images, deleting the docker image and re-pulling, but i never get that sweet sweet [init] Resolving type given PAPER in the logs.

Do you know what stupid mistake i'm doing here and i'm too tunnel-visioned to not see? Please and thanks for your attention
Here are my configs:

Do you know what stupid mistake i'm doing here and i'm too tunnel-visioned to not see?

Yes 😀 You still have MOD_PLATFORM declared. That and the modpack take precedence for deciding the server type -- Fabric in this case. Remove that and the modpack related variables.

Also, I recommend leaving out PAPERBUILD and use the default. They release updates quite often and it will be tedious for you to keep changing that. VERSION is what really matters to remain compatible with your clients.

Amazing, that's for my misunderstanding of minecraft servers. I assumed that since paper add-ons are called "plugins" and fabric's are called "mods" you could have both at the same time on the server.
Thanks a lot for the advices, time for me to hang out in the config files a lil bit more!
