powers lizzy

I added some new mods and updated old ones to my forge server and they will run successfully but the moment I try to join ill briefly load into the world and get booted with the message, internal server error. The mods in question work fine on singleplayer and removing too many from the server causes it to stop working so I cant be sure which one is causing the problem... any ideas? server log: https://pastebin.com/hGH8UUjm client log (from modrinth app): https://mclo.gs/a3oOUGY
