It is recommended to pass the name of the feature layer to the tool and set the symbology of the feature layer fetched from the map. This is more efficient than creating an output feature layer parameter to set the symbology.

Workaround

Code to take an input feature layer, where p0 is the text name of the feature layer, and update the symbology from the layer as fetched from the active map.

p0 = parameters[0].valueAsText # set p0 in the pyt p0 = arcpy.GetParameterAsText(0) #set p0 in the script tool, aprx = arcpy.mp.ArcGISProject('CURRENT') lyr = aprx.activeMap.listLayers(p0)[0] symb = lyr.symbology symb.updateRenderer('UniqueValueRenderer') symb.renderer.fields = ['LABEL'] lyr.symbology = symb.

Otherwise, for a script tool, create an output feature layer parameter that is derived from the input layer. In this scenario, p0 is set to p0 = arcpy.GetParameter(0) in the main function. Then, at the end of the execution, set the output parameter: sym = p0.symbology sym.updateRenderer('UniqueValueRenderer') sym.renderer.fields = ['LABEL'] p0.symbology = sym arcpy.SetParameter(1, p0)
