it? It kinda looks like you have a "table" object serialized somehow rather
than primitive.
@potiuk In looking at the code again, and the actual Log message, it looks
like I accidentally tried to serialize a whole table row instead of the value
of the first column of the table row.
>Loaded BQ data with max
data-landing.api.users_20220928_.updated_at=Row((datetime.datetime(2022, 9, 28,
16, 57, 18, 752695, tzinfo=datetime.timezone.utc),), {'f0_': 0})
This serialized row then causes issues in XCom. I'll see about fixing it.
