If you pass a wrong param ther is no error code.
That leads to this type of error:

# sudo bash -c './change-gdm-background' && echo "DONE" || echo "ERROR"
Image file not found or wrong color hex code.
Please, submit a .jpg or .png image file or a valid hex code.
Usage: sudo ./ubuntu-20.04-change-gdm-background /path/to/image.*g
Usage: sudo ./ubuntu-20.04-change-gdm-background \#yourhexcode
DONE
