Start at the us-east-1 Amplify Hosting monitoring URL for app d3naf5yooank88 and verify whether the metrics panel remains stuck loading. The payload names no repository files or tests, so trace the dashboard request from this entry point; done means the metrics panel displays instead of spinning indefinitely.
