Workaround

Create an in_memory copy of the input polygon feature class, delete the identical field used in the field mapping object, and then pass it into the spatial join.Code example below:# import modulesimport arcpy, os# Data: Specify location of test datahome = arcpy.GetParameterAsText(0) #r"<a href="file:C:/ArcGIS" target="_blank">C:\ArcGIS</a> Testing\Python Testing\957244 - Field Mapping"# Data: Local VariablespolygonFC = home + os.sep + "Polygons.shp" pointFC = home + os.sep + "Points.shp"idFieldName = "regID"scratchSJshape = "temp_sj.shp"scratchDirectory = home + os.sep + "Scratch" + os.sep# Process: Check if scratch folder exists and delete itif arcpy.Exists(scratchDirectory[:-1]): arcpy.Delete_management(scratchDirectory[:-1])# Process: Create scratch folderarcpy.CreateFolder_management(home, "Scratch") # Process: Create Field Mappings ObjectfieldMappings = arcpy.FieldMappings()index = fieldMappings.findFieldMapIndex(idFieldName)# Process: Populate Field Mapping ObjectnewFieldMap = arcpy.FieldMap()newFieldMap.addInputField(pointFC, idFieldName)newField = arcpy.Field()newField.type = "String"<a href="http://newField.name" target="_blank">newField.name</a> = "TestField"newField.aliasName = "TestField"newField.editable = 1newField.isNullable = 1newField.length = 250newFieldMap.mergeRule = "Join"newFieldMap.joinDelimiter = ", "newFieldMap.outputField = newFieldfieldMappings.addFieldMap(newFieldMap)# Process: Create polygon layer in memory and remove id fieldmemPoly = r"in_memory\polyFeature"arcpy.CopyFeatures_management(polygonFC, memPoly)arcpy.DeleteField_management(memPoly, idFieldName)# Process: Spatial join the point and polgon featuresarcpy.SpatialJoin_analysis(memPoly, pointFC, scratchDirectory + scratchSJshape, "JOIN_ONE_TO_ONE", "KEEP_ALL", fieldMappings, "INTERSECTS")# Process: Return output to model/displayarcpy.SetParameter(1, scratchDirectory + scratchSJshape)# Process: Delete in_memory featurearcpy.Delete_management(memPoly)
