I am following these instructions to create a printing service in Enterprise 10.9.1:
https://enterprise.arcgis.com/en/server/latest/publish-services/windows/tutorial-publish-additional-layouts-for-printing-with-arcgis-pro.htm
I have followed all the instructions and when I get down to the "Share a printing web tool to the ArcGIS Enterprise portal" portion I am getting an error:

Others say Report Item ID instead of Layer Item ID, but you get the IDea 🙂
Any one know why I'm getting this error and how I can fix it?
Thanks in advance.
