Debug a broken application
Reproduce an application failure, inspect the relevant Jotsu logs, and ask Codex to make the smallest focused fix and verify it.
What you will do#
Find the first relevant error and verify a focused repair.
1. Reproduce the failure#
Write down the exact action, expected result, actual result, and approximate time.
2. Inspect the logs#
Open the application’s Dev tab. Reproduce the action once, then find the first related error in Dev logs.
3. Ask Codex to investigate#
Open Build. Give Codex the reproduction steps and ask it to identify the root cause before making changes. Include a redacted log excerpt.
4. Verify the fix#
Repeat the original steps. Confirm the expected result, reload the page, and check Dev logs for a successful outcome.
What happened#
The diagnosis used a repeatable failure and server evidence, so the repair could remain limited to the responsible code or configuration.
