My datapack works in SP but not in MP

Hey guys. Im new here and I don't even know why am I trying. But I really want to make custom recipes for my personal MC server. BUT
While simple datapacks works in single player world, they don't in multiplayer. (fabric 1.20.6 server) 
The datapacks that I downloaded works just fine, but mine doesn't.

I tried with https://misode.github.io/ and then I tried it by myself but every time the same result. 😦
Does someone have any idea why it's not working? 
Thank you guys and sorry for my bad English.
