Forge Server Help Please!

I’m trying to add sponge to my Beyond Reality Farscapes server, but I keep getting an error. I’ve already checked to make sure i’m running the correct Sponge and Forge versions… The last thing I can think of is removing the mods one by one until one does the trick, and I don’t want to do all that if I don’t have to lol
Here is the log(what’s Important anyway):
