OpenAI API 401 Incorrect API Key Provided - Fix Runtime Env and Bearer Header
Fix the OpenAI API 401 Incorrect API key provided error by checking the key your app loads at runtime, verifying the Authorization: Bearer header, matching the project or organization context, restarting the process or deployment, and confirming the fix with one minimal request.
Steps covered:
1. Reproduce the 401 with a minimal API request.
2. Compare the runtime OPENAI_API_KEY value with the key your app should use.
3. Replace stale environment variables safely.
4. Check the Authorization: Bearer $OPENAI_API_KEY header format.
5. Confirm project or organization context when applicable.
6. Restart the shell, server, worker, or deployment.
7. Verify the request returns 200 OK.
