Problem: You're seeing
dashboards cached_results miss for id <your_dashboard_id> in the JS console on an embeeded dashboard
Explanation: No need to be alarmed. This message is harmless. It's logged by the front-end code whenever the /cached_results endpoint was not used to accelerate the dashboard load and that endpoint is never used for embedded dashboards.
