This error occurs in the server console due to client side mods existing in the server pack.

How to fix:
remove the mods from the server pack mods folder but keep them in the client side folder:
LootBeams
keymap
Great Scrollable Tooltips
Better Clouds

Reproduction steps

1. download server pack 0.4.3
2. run it with start.bat

Relevant log output

Oh it needs to be added to the server export blacklist, thanks
