Server doesn't start up [main/FATAL] [minecraft/Main]: Failed to start the minecraft server java.lang.NullPointerException: null

[CometStorm]

I've been trying to get this server to work for a couple of hours now, but since I'm not too knowledgeable with this, I don't really know what is the problem. Right after this, it tells me to press any key to continue and then cmd exits.

[kiou.23]

are you making a mod, or just having issues to use mods?

[CometStorm]

I have issues using mods on a forge server. It is a modpack I created via curseforge and I'm trying to figure out what is causing the error.

[Edit] I just noticed I put this topic in the wrong place. I am sorry.
