1.18.2 - 2.3.0-b: server crashes trying to load client
My buddy and I are playing Wold's Vaults (a fork of Vault Hunters 3), and they said I should install this major update on our server.
https://www.curseforge.com/minecraft/modpacks/wolds-vaults
My server is running Kubuntu 24.04
(I installed openjdk-17 with apt, not sure why it isn't using that, I could not find it on my system)
I downloaded the mod with
wget https://cdn.modrinth.com/data/uCdwusMi/versions/trPCtnMC/DistantHorizons-fabric-forge-2.3.0-b-1.18.2.jar
First Fatal Error:
I tested the same .jar file on a dedicated server with no other mods and it works fine. (I did not join with a client though).
Server loads up fine without DH 2.3 installed.
I attached the crash log.
Mods list of the 415 mods (ls ./mods/) is attached as well.
Any ideas or tips would be appreciated, though we prob wont be playing any MC until we finish the TrailMakers 2.0 campaign.CurseForge

"I can see the issue now. The getMinecraftVersion() method is trying to use Minecraft.getInstance() which is a client-only method. For versions before 1.19.2, it's using the client-side method to get the version, while for 1.19.2 and later it's using the server-safe SharedConstants class."I didn't ask it why it worked fine without other mods, although I did realize that maybe it was the modloader version doing it ...

i hate to inform you, but a /binary search might be necessary
Try a binary search and figure out which mod is causing it.
So disable half of the mods, see if issue is still there, if yes disable half again etc etc until you find the mod that's causing the issue.
Yeah figured it prob would be, but I don't need it enough to try that
Client side DH works perfectly fine on own
Also I'm not actually sure that would work because some of the mods are so closely tied together
I might try it next week when I have more time
yea fair enough
I might actually try messing with the source and compiling to see if I can make it work
If I figure it out I'll post what I found out
got it working
