Server crash on startup

[TheHorseFly]

When I try to start the mod on a server, it gives this error:

[00:13:56] [main/ERROR] [ne.mi.fm.lo.RuntimeDistCleaner/DISTXFORM]: Attempted to load class com/lightning/northstar/mixin/dimensionstuff/FogRendererMixin for invalid dist DEDICATED_SERVER
[00:13:56] [main/FATAL] [mixin/]: Mixin prepare failed preparing dimensionstuff.FogRendererMixin in northstar.mixins.json: org.spongepowered.asm.mixin.transformer.throwables.InvalidMixinException Attempted to load class com/lightning/northstar/mixin/dimensionstuff/FogRendererMixin for invalid dist DEDICATED_SERVER

it then crashes, spewing a bunch of log stuff (can put in pastebin if needed)

[BraveJamstar]

I have the same error. The error seems to be caused by the mixins for the mod. These mixins weren't made to run on the server version of forge so that's why it was crashing as said with "invalid dist DEDICATED_SERVER." I was able to get northstar to run by removing these mixins but the game was extremely broken and nothing from it worked. I did this by removing the mixins but also adding icu to src/main/java/com. The game would flip out with liquids and blocks. For example if a placed a door. It would turn into water. If I placed a gear it would turn into water as well.

ICU: https://gitlab.com/gitlab-org/build/omnibus-mirror/libicu/-/tree/93fde1c459ec73272361b311ee0258ecd57224cb/icu4j/main/classes/core/src/com

I am also seeing the same issue running the mod on a server, same error as above for me.

OS: Ubuntu 22.04
Forge Version: 1.19.2 - 43.3.5
Northstar version: 0.1a

[BraveJamstar]

As of 8/4/24, The dev fixed multiplayer. However, adding the mod to a server still crashes it. What I was able to find out is adding ICU from earlier to the server mod fixes the crash and the game runs normally. When doing this for the client, the game doesn't launch. It looks like if the dev wanted to support the server version of forge. He would have two separate mods, one for the server and one for the client. So right now until the dev adds the code to make the mod compatible with the server side. We'll most likely have to make our own server side mod manually by adding ICU and building from source.

Edit: Thank you, lightning2401 for all the work that you have put into this mod. I'm gonna do more testing and then I'm gonna make a pull request with my fix.

[BraveJamstar]

Turns out you don't need to build another file at all. You just need another mod known as icu4j on the server side. After that the server starts without any modification to the file. Just put the file in your mods folder. I will leave a link to the jar file I have. Sorry for any confusion I may have caused earlier. But I have this helps

when I use this mod, it still gives the same error

[BraveJamstar]

Uh ok. That's strange. It worked for me when I did it. What version of minecraft are you using? Also just making sure, you have geckolib and create as well, Right?

I can give you my build if you want to try with that.

1.19.2, and I have both geckolib and create, still the same error

[OutCraft-Mods]

I think I fixed this issue in my PR #40, can anyone of you try it out?

[BraveJamstar]

That might actually work. I'll start testing it out.

[BetaKale]

@BraveJamstar Did you get it working?

[BraveJamstar]

I did get it to work. I loaded into the game and everything worked. So turns out the change that OutCraft-Mods made to the code actually fixed the error. Now we wait for the dev to merge the code. For now we can compile from OutCraft-Mods' repo. Should work fine.

Anychance you could either send me your complied mod or teach me how? I haven't been able to figure out how to do it. My discord is BetaKale if you just want to dm me

[BraveJamstar]

I can send you the compiled mod. But if you'd like to learn how to do it. First, You need to install java if you don't already have it. Second, download the OutCraft-Mods' repo and open a command prompt in that folder. You can do this by clicking on the path and typing in cmd. Next, Run gradlew build and wait. This might take a few minutes. The built file should be in build/libs. This is for windows.

The path thing I'm talking about:

But if you want my built file:
Northstar-1.19.2.zip
You need to use this file for both the server and the client.

Hope this helps.

[OutCraft-Mods]

Ohh you send it as zip! I tried uploading a jar but GitHub didn't let me... learned something new I guess!

not to sound like a broken record, but that is still giving me the same error. I may just be dumb but at this point ill just wait to add it to my modpack till its officially fixed.
