My "Fabric mod" wont run

so im testing out MCreator for the first time and I tried to make giornos theme into a disk, I made the disk and when I try to export/test my "mod" if you would so call it, it says "Your workspace contains mod elements that don't compile and could not be exported. No mod file was generated" then the script that poped up when it was trying to export it says
