[GIS] Error TypeError: ‘NoneType’ object is not iterable

arcmaparcpypython-script-tooltypeerror

I am trying to batch process KML polygons from a folder into a temp geodatabase.
From there, Iif this works and runs then I am trying to Append the polygons to result to a Server connection (Postgres withe append layer). Going to use here the ModelBuilder when the script runs.
But I am stuck on a error

Traceback (most recent call last):
File "C:\Users\Bjorn.tenBroeke\Documents\Bjorn\KML.py", line 20, in
for kml in arcpy.ListFiles('.KM'):
TypeError: 'NoneType' object is not iterable
Failed to execute (Script).

# Name: BatchKML_to_GDB.py
# Description: Converts a directory of KMLs and copies the output into a single fGDB.
#              A 2 step process: first convert the KML files, and then copy the featureclases

  for fc in featureClasses:

    fcCopy = fgdb + os.sep + 'Placemarks' + os.sep + fc    
    arcpy.FeatureClassToFeatureClass_conversion(fcCopy, MasterGDBLocation, fgdb[fgdb.rfind(os.sep)+1:-4])


# Clean up
del kmz, wks, fc, featureClasses, fgdb

Best Answer

The error means the workspace folder/directory does not exist (r"C:\DATA\KML"). Check to make sure the "KML" folder/directory exists.
