Server keeps stopping whenever I add BYG to the mods folder

So I've tried multiple times to add BYG to my server but it always crashes, saying that there's no data fixer registered for byg:boat and byg:chest_boat, is there any way to fix this?

Crash log: https://mclo.gs/1cXVL3L

Yes, I have tried it with BYG on its own in a fresh server, it gives the same crash report

Yeah I made a bug report on github but so far no one has responded for a week now
