1.21.1 NeoForge Server

Error when adding ForgifiedFabricAPI and nothing other

[main/ERROR] [common.asm.RuntimeDistCleaner/DISTXFORM]: Attempted to load class net/minecraft/client/gui/screens/Screen for invalid dist DEDICATED_SERVER

Its always giving me this error, but everything seems to work, so I only want to know if its a common thing and nothing to worry about.
