[GitHub] [beam] damccorm opened a new issue, #21034: datetime.date not working with Distinct()

damccorm opened a new issue, #21034:
URL: https://github.com/apache/beam/issues/21034

   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 '<class 'datetime.date'\>', 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?
