8.44Another scenario

“The Mule flow works in QA but fails in production with INSUFFICIENT_PERMISSIONS. What do you investigate?”

Walk through:

1. Which production integration identity is being used?

2. Object permissions?

3. Field-level security?

4. Record-level access/sharing?

5. OAuth/client configuration?

6. Did schema or permission-set deployment differ?

7. Is the Mule configuration pointing to the correct org?

8. Compare with QA identity/configuration.

That is a very credible troubleshooting answer.
