Null String Not Allowed Crash Modpack

[ChikaDrevni]

So i was trying to make a modpack on my own, just some kitchensink kind of stuff and there is a lot of mods. Sometimes it just crashes and says null string not allowed error, and sometimes it says reason unknown. here is the log of the client. I have tried disabling several mods that i thought would crash the minecraft but couldnt pinpoint which one it is.

Appreciate the help

Maybe an issue with vanillafix

no, i added vanillafix after it started crashing to see why it crashes

Make a test just with Forge - if this works, add the mods one by one or in groups
