I am just trying to help to solve this release blocker by fixing: https://github.com/apache/beam/pull/11226#issuecomment-604729044. However I didn't find a way to directly append the fix to #11226 Please let me know if you still prefer to use #11226, we could figure a way out. ------------------------ Thank you for your contribution!
