Crashes on some servers

[kittech0]

There is small issue, the mod simply loads on server and instantly crashes.
If it could be possible to simply not load the mod on server :p

[Gaming32]

This mod shouldn't crash on the server. Please send logs.

[Gaming32]

This mod assumes all java.* modules exist. If these modules are not present, it's because this hosting provider is using a non-standard JRE, and I would consider such a host unacceptable for general modded use.

[GaetanQu]

Well everything works well since I remove your mod from the server. And first of all, if it is a screen (I mean, mod loading screen is supposed to be a screen), why admitting it should run onto servers ? I made a script that downloads only server-side mods in the server mod folder, and it took me a while to get through the uncaring of mod developers concerning the env key of the fabric.mod.json file. I had to find the project ID into the modrinth.index.json download link, then ask the Modrinth API if the mod environment has been set either to client or server or both, that had to work bc it's almost well indicated at least on the platform, and still this mod is there, useless in this context, standing alone in his corner crying not to be removed. Why is it server side ???

[Gaming32]

Mod Loading Screen logs when mods are initializing themselves (instead of showing a screen) when on a server, which makes it a very useful tool for debugging mod initialization. I myself have used it for this numerous times. However, my call to see if this behavior should be used is the very call that is failing.

[GaetanQu]

what do you mean "Mod Loading Screen logs ..." ? Fabric does it by itself isn't it ?
Here's an example with the same server without Mod Loading Screen :

Mod Loading Screen logs each mod as it is initialized. This is not functionality builtin to Fabric. What you're talking about is a list of mods that will be loaded.

[GaetanQu]

okay I understand better, but still, what's the problem with my server ? I host it on my VPS and I think my JRE is up to date. And as said before, it works with any other mod

[Gaming32]

Can you please try again with MLS 1.0.5 and send the log?
