ran into the same problem, convert datatime.date to Timestamp helps

The Timestamp helped. Though, I had to make it time zone aware. Otherwhise you get the error: TypeError: Cannot compare tz-naive and tz-aware timestamps" The solution on my side: (row["created_at"] > pd.Timestamp(2022, 1, 1, tz="UTC"))
