Root Cause Analysis
The root cause of the incident was a flaw in the ticket initialization logic. When the requester ID was undefined, the system attempted to retrieve it based on the ticket key, leading to errors whenever any field change occurred in the ticket UI. The introduction of new logic to read the user ID from the user profile page and set it to the requester ID inadvertently set the requester object to undefined, which broke the expected functionality.
Resolution
To resolve the issue, the problematic update was reverted.
Remediation Items
- Fix flawed code: Ensure that the system correctly sets requester data when creating tickets to prevent blank entries.
- Add automatic testing: Create a test to check that the ticket save process correctly handles requester information.
- Confirm Manual Testing: Require deployers to manually test changes on “canary” PODs and confirm that everything works before deployment.
- Improve Monitoring: Set up monitoring to alert on browser errors, such as “something went wrong,” to quickly identify issues.
