SW PCB: Blank Outline File

Hello

I've been going around in circles for a while to figure out how to get the outline out of my pcb board. When I generate the gerber files, they are well written but the GKO file that corresponds to the outline is empty and yet very present. I can't find the mistake. I specify that I have holes on the board and that I created this same board in collaboration with solidworks.

If anyone has an idea.

Thank you for your help
