If you unpack the error with unpack_errors, you should see the location. 
  E.g.:

   try:
       result = UserScheme().to_python(request)
   except Invalid, e:
       err = e.unpack_errors()
       # then look at err['phone_numbers']
       # should have None for correct fields, a string for
       # incorrect fields
