Automator code signing requirement

I created a simple Automator script to change my desktop wallpaper. I since have installed a second screen and wanted to extend my desktop on to this, and use my script to change the second screen wallpaper.

I ran in to this error: 'unsealed contents present in the bundle root' which makes no sense to me. There's a huge mass of nonsense about code signing and needing a developer account. Can this be disable for this application? It just changes my wallpaper pictures from my dog as a puppy to 1 year.

Thank you for any advice.

The applescript I added is below:

on run {parameters}

tell application "System Events"

tell desktop 2

set picture to "/Users/nick/Pictures/Dufus1y-230914.jpg"

end tell

end tell

end run
