ValueError: Search API cursor pagination day is out of range for month

[sentry-io]

This error is quite weird. The cursor shows a request_date of 1990-08-32.

The request_date is extracted from the cursor or set using datetime.datetime.now().date() if it's the first page.

This could just be an isolated case where the user altered the cursor
