Server side permissions for embed programmatic filtering not working with private embed

I am able to access my dashboard with the embed links set to private using server-side permissions. However, when I log into an account that have filters set, I get the following error:

{"status":400,"statusReason":"Internal Server Error","path":"/embed/pages/5yv8Z","toe":"6EH2UGS74M-ES1C9-R929I"}

I am fairly new to all of this and trying to figure out why the filtering would be blocking access.
