Language Provider Needed??

I don't know what to put, but basically I'm trying to make another modded server on aternos, but whenever I try to start the server up, it crashes.

When I check the logs, its saying that a mod named "Sit," needs a language provider

net.minecraftforge.fml.ModLoadingException: Mod File sit-1.16.2-v1.3.jar needs language provider javafml:33 or above to load

Here is the log, https://mclo.gs/0zZKRIU

1.16.1 (32.0.108)
