From Fedora Project Wiki
Saw the following error at the final step:
1 error prohibited this record from being saved:
failed to get the deployable definition: image with uuid #{image-id} not found
It's not clear from the documentation whether that needs to be replaced with an actual image ID, though I tried that and that didn't work either.
