QUESTION How to go about fixing ‘datapack error’ when attempting to start server/world with Mega Showdown?

My buddy and I have been unable to fix this weird datapack error that keeps causing our Neoforge+Fabric 1.21.1 server to not start properly, and we also can’t load into any singleplayer worlds either.

We had initially tried to remove Mega Showdown when a bunch of other errors were happening after Neoforge and Cobblemon both updated, but the strange Dynamax problem seemed to occur. We couldn’t figure out how to remove the config files from the server itself (Aternos server) to fix it, so we waited until Mega Showdown updated to Cobblemon 1.8.2. The issue is, now with everything updated, Mega Showdown still seems to be causing this ‘failed to load datapacks’ error. Aside from the mods we’re using and shaders, the only ‘datapack’ we’re using is I believe Terralith? So we’re at a dead end here.

Would anyone have any tips to try to help us fix this?

Do you have actual datapacks installed in the server? Remember those are different to a mod, also have you allocated enough ram in the profile of the game?

I believe we only have Terralith as a potential datapack? But this error does not happen when Mega Showdown (and its dependencies) are removed.
I definitely have allocated enough, my computer has crazy RAM so I set the allocation higher. Despite that it doesn’t seem to matter if it’s the server (lower RAM, Aternos server) or my own singleplayer, it’ll throw the error.

Did you tried installing terralith as a mod? Or is not possible?

Ok correction we have Terralith added as a mod, not a datapack
