Hi @HaeB and @phuedx! The whitelist for the ReadingDepth EventLogging schema is keeping permanently fields that contain both unique session ids and page ids. Per our data retention guidelines, we cannot keep those two items together for more than 90 days and therefore one of them should be removed from the whitelist.
Please let me know which one of the following two you'd like to keep:
- Session IDs => keep sessionToken
- Page IDs => keep pageTitle
