Please help proper installation on server

[prime pendant]

Hi Everyone!
I need help and understanding on how to properly install From the Fog.
I've tried installing it on 1.21.11 but seems like not working so I downgraded to 1.21.10 which is listed as supported version.
I've been trying for a couple of hours now to make it work on our local network Fabric server but always getting the error attached.

I have tried Fabric API + From the Fog v1.11.2.jar but the same. I also tried putting the datapack in the datapack folder of the world folder in the server but still getting the same issue.

Am I missing something? I am trying to get this server for my two boys who are excited to play the mod. Please let me know what am I missing.

Thank you.

The pack metadata error can be ignored, FTF will still work

Hi, Thanks for the response. I am trying to get the command to work but it says unknown command. Also tried in single player to check and the reason why I am thinking its not working 😥
On single player, I tried the mod, the datapack and both at the same time.

Could you try typing the command /datapack list and sending a screenshot of what it shows? ^^

Sorry for the delay, just got home from work.
I redownloaded the mod and datapack. This is currently with the mod in mods folder and datapack in the world's datapack folder. I also have Fabric API, fallingtree mod with the library for it.jar.

You should only install FTF once, either the datapack + resourcepack, or the mod ^^

Now you've got it installed twice which could break the entire pack :P
