Cant add FeatureSet type to WebMap

[Oliver_Sandoval_e]

Hello,

I'm new to the Python API, but would anyone be able to tell me possible reasons why I cant add a FeatureSet to a Web Map even though its a valid input for "add_layer" according to the API documentation? Nothing shows up when I add the layer, I can add the un-queried layer fine.

My Versions are Portal 10.8.1 with Pro 2.8 and am working with a hosted feature layer.

Thank you for your time!

Sorry to ask the obvious, but does that query return records? Everything seems to be in order in your screen.
