Mod prevents server from starting

Mod works perfectly fine in single player,  but prevent server from even starting if placed in a server.
"Could not execute entrypoint stage 'main' due to errors, provided by 'lanas_stuff'"
Mod only contains 3 blocks and a couple of music discs

Is there anyway to fix this?
