Description
I was using 2.28.0 and running a standard Distinct on a PColl of datetime.dates without problems.
After upgrading to 2.31.0, I'm getting this error:
TypeError: Unable to deterministically encode '2020-12-02' of type '', please provide a type hint for the input of 'Get the unique dates from prices/Group/GroupByKey' [while running 'Get the unique dates from prices/ToPairs']
Had convert the date to str and back to date after running the Distinct() to preserve the date type. Any clues?
