Troubleshooting an 'unauthorized' error in real-time.

1. Initial Pipeline Failure Assessment

When a CMS publish pipeline fails, start by identifying the immediate error.

• Recognize the 'unauthorized' error message.
• Note the exact point of failure in the pipeline.
• Confirm the build was otherwise complete before the failure.
• Understand this is a live, unscripted debugging scenario.

2. Accessing and Reviewing Error Logs

Dive into the logs to find specific details about the failure.

• Locate and open the relevant error logs.
• Read through the log entries to find the root cause.
• Identify any specific error codes or messages provided.

3. Investigating Potential Causes

Formulate hypotheses about why the pipeline is failing.

• Consider API key issues on the website.
• Evaluate if external service configurations are correct.
• Think about recent changes to the CMS or pipeline.
• Hypothesize about network or connectivity problems.

4. Utilizing Debugging Tools

Employ tools to help diagnose and understand the problem.

• Use a code editor like Cursor for analysis.
• Step through the code or pipeline configuration.
• Examine variable states and function calls.
• Search for similar errors or documentation online.

5. Testing and Implementing Fixes

Apply potential solutions and test their effectiveness.

• Copy and paste potential fix snippets.
• Modify configuration settings based on findings.
• Test the proposed fix in a controlled environment.
• Re-run the pipeline after applying a change.
• Iterate on fixes if the initial attempt fails.

6. Verifying the Resolution

Ensure the pipeline now completes successfully.

• Confirm the 'unauthorized' error is gone.
• Check that the CMS content was published correctly.
• Monitor the pipeline for any new or recurring issues.
• Validate the entire publish process end-to-end.

7. Post-Resolution Actions

Reflect on the process and document learnings.

• Document the cause of the failure and the solution.
• Consider adding automated checks for this specific error.
• Share findings with the team if applicable.
• Reflect on the systematic approach to debugging.

Approach pipeline failures calmly and systematically to find resolutions.
