Your Actions

I attempted to start a server after unzipping the official server zip on the website and running it on a Ubuntu 24.04.4 LTS vm.

I also tried different launch options such as:
/usr/lib/jvm/java-17-openjdk-amd64/bin/java -Xms3G -Xmx5G -Dfml.readTimeout=180 -Duser.language=en -Duser.country=US @java9args.txt -jar lwjgl3ify-forgePatches.jar nogui

As this seemed to be related to issue #22845 to me?

[NateZeNarwhal]

Is that causing the null entry on a recipe component? Or is this unrelated to the crash?

[PLASMAchicken]

most likely its related to the crash. But this error usually doesnt happen in a freshly downloaded GTNH 2.8.4 instance..
