I'm trying to write a Web Tool (GP Service) that references a hosted feature service that I have published in Portal.
For example: I want to do a spatial join (intersect) with an input point location to a hosted feature service boundary. If I reference the feature service REST endpoint in the operation, it works fine. However, publishing as a web tool requires that I choose 'copy' the data and cannot access it by reference because it says the service is not registered with the server.
Ideally, I'd like to write a Web Tool (GP Service) that operates by reference to the actual data and not needing to copy any data.
I tried using a combination of ArcGIS API for Python and ArcPy. Instead of referencing the item by URL, I used `gis.content.get(id)` to get the item by ID and tried passing the feature layer `.layers[0]' into the Spatial Join operation. That didn't work.
How do you write ArcPy scripts to work with data/services as hosted feature services without needing to copy any data when publishing GP Services?
