The Issue

The issue should come from the colon in the name. After I replaced it with underscore, the error was resolved.

  with open(filename, "wb") as file:
         ^^^^^^^^^^^^^^^^^^^^
OSError: [Errno 22] Invalid argument: 'PRC_FUEL_20190101T00:00-0000_20190131T00:00-0000.6.zip'

Which OS are you running on? This was working for me on Mac.... I'll look into changing this so that it is OS agnostic.

Also we should change this so the fuel prices are only downloaded when interconnect==western

I am running on Windows. Now I added following lines to make it work

        startdatetimename = startdatetime.replace(":", "")
        enddatetimename = enddatetime.replace(":", "")
        filename = f"{queryname}_{startdatetimename}_{enddatetimename}.{resultformat}.zip"
