I am trying to create a geoprocessing service that can sense which layer that the user selected from. I have created a sample script to show what I have tried so far. It has a parameter called "Selection" which is of data type "Feature Set" and a string output parameter.

catalogPath: in_memory\{EA09D0E5-F384-4742-A3FB-1A865BAEF30A}

childrenExpanded: True
dataElementType: DEFeatureClass
dataType: FeatureRecordSetLayer
extension:

fullPropsRetrieved: True
metadataRetrieved: False
name: {EA09D0E5-F384-4742-A3FB-1A865BAEF30A}
path: in_memory
feature_layer_as_text: in_memory\{EA09D0E5-F384-4742-A3FB-1A865BAEF30A}<SPAN class="line-numbers-rows"><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN></SPAN>One way I can tell which layer was selected is by using "arcpy.ListFields(feature_layer)" and figuring out from the fields which layer was selected. Is there a better or more direct way to fetch the name of the layer that was selected in web app builder?
