From a missing .png extension on Slack screenshots to a CSV download 500 error caused by PostgreSQL’s idle_in_transaction_session_timeout killing the metadata DB connection mid-download. The trickiest one required tracing through both Superset server logs and RDS error logs to discover that the error connection and the causal connection were different — the SSL error was on the metadata DB, not Redshift.
