In the latest version of the python client (python is 3.6), If a query with a time field is submitted with fetch_results set to true, iterating through the results object returned will always fail with a value error. Here is the error message:
~/pythonprogs/prog1/src/lenspythonclient/contrib/clients/python/lens/client/query.py in <genexpr>(.0)
115 def _parse_line(self, line):
--> 116 return list(self._mapping(self.header.columns[index].type (line[index]) for index in range(len(line)))
118 def get_csv_reader(self, file):
ValueError: invalid literal for int() with base 10: '2018-06-30 00:00:00.0'
It seems that the actual type of the date field is timestamp, and is not converted correctly.
