After cleanup part, command not found in the prime directory, but it's there

Thanks @lucyllewy. I have the standard cleanup part that I found here: Reducing the size of desktop snaps

  cleanup:
    after:  # Make this part run last; list all your other parts here
      - alpha
    plugin: nil
    build-snaps:  # List all content-snaps and base snaps you're using here
      - core18
      - gnome-3-34-1804
      - gtk-common-themes

    override-prime: |
      set -eux
      for snap in "core18" "gnome-3-34-1804" "gtk-common-themes"; do  # List all content-snaps and base snaps you're using here
          cd "/snap/$snap/current" && find . -type f,l -exec rm -f "$SNAPCRAFT_PRIME/{}" \;
      done

So the way I interpret your advice is to remove the “core18” from the for loop. I’ve tried that and the proble persists.

Skipping prime gnome-3-34-extension (already ran)
The command 'bin/alpha' was not found in the prime directory, it has been changed to '/usr/bin/python3'.
Failed to generate snap metadata: The specified command '/usr/bin/python3 $SNAP/bin/alpha' defined in the app 'alpha' does not match the pattern expected by snapd.
The command must consist only of alphanumeric characters, spaces, and the following special characters: / . _ # : $ -
