Forge Server 1.12.2 Specified entry Block not in regestry

[Hyokuani]

I made a modpack with all mods I like on 1.12.2.

In Minecraft Local World it works but if I create a forge server its giving me that error and I have no idea what to do now.

 

Connection Lost

Internal Exception: java.lang.IllegalArgumentException: The specified entry Block{null} hasn't been registered in registry yet.

 

What should I do now?

I attatched some files idk if they are usefull

 

Are there Mods that should not be in Server folder?
