I made a Fabric mod that adds a backpack with a GUI and when I play the mod in single player everything works. I exported the mod and added it to my server but the GUI doesn't open and I get an error.

I don't know how to fix this.

Getting the same issue myself. Not sure if this is fabric related or mcreator as as a whole? but would be great if it was working on servers too
