I am trying to run a code to fetch timeseries based on some tags available in a project. While I execute the same code using jupyter notebooks in CDF online-notebook feature, the code runs fine. 

When I am trying to run the same code script in local after setting up connectivity using interactive-login and then when I run the timeseries retrieve code, I am getting an error. Please help.

Code:

from datetime import datetime, timezone
utc = timezone.utc


pi= client.time_series.data.retrieve_dataframe(external_id=['pi:2FC1898.DACA.PV','pi:2TC1066.DACA.PV','pi:LAB_133-X013_APIGRAVOB','pi:2FC1898.PIDA.OP'],
                    start=datetime(2023, 1, 1, tzinfo=utc),
                    end=datetime(2023, 5, 1, tzinfo=utc),
                    aggregates=["average"],
                    granularity="1d")

Error- Traceback:
