As the title suggests, I had successfully published a new Web Tool (Geoprocessing Service) to a Federated ArcGIS Server Site. It created the item in the portal just fine too, however I saw a problem with it and decided to remove it and start over.
The issue: I used ArcGIS Server Manager to stop and delete the service rather than deleting the associated item on portal. It seemed to be ok and deleted the portal item and of course it no longer exits on the AGS site or anywhere.
Now when I go to publish the Web Tool I get an error message in Pro stating it cannot publish because the item exists.
Any help on how to troubleshoot is appreciated.
