Información adicional
The MakeFeatureLayer_management tool does not return a layer object but instead a result object. Extract the layer from the result using the appropriate index. In this case, it is [0]. The object at index 0 in the result object is the layer to add. Use the following code: temp = arcpy.MakeFeatureLayer_management(r"C:\Temp\GreatLakes\GreatLakes.gdb\GreatLakes", "TestOutput")[0] p = arcpy.mp.ArcGISProject('current') m = p.listMaps('Map')[0] m.addLayer(temp)Solución alternativa
