----------------------------------------
Summary: datetime.date not working with Distinct()
Key: BEAM-12717
URL: https://issues.apache.org/jira/browse/BEAM-12717
Project: Beam
Issue Type: Bug
Components: sdk-py-core
Affects Versions: 2.31.0
Reporter: Sebastian Kretzig
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?
