Exception "Keys only queries do not support IN filters." #4
Description
The pipeline filter is
'filters': [("due_date", "<", due_date_before),
("due_date", ">", None),
("status", "IN", ['planned', 'working'])]
The result of pipeline with input reader set to 'mapreduce_utils.DatastoreQueryInputReader' is an exception below.
Would you have any suggestions for a quick workaround?
