Fix RequestFailedException

✅ Solution

RequestFailedException in Azure Functions often arises from transient network issues, authentication problems (especially with Managed Identities), or Azure service unavailability. To resolve it, implement retry logic with exponential backoff around Azure SDK calls, and ensure your function's Managed Identity (if used) has the necessary permissions and is correctly configured in both the function app and the target Azure resource. Consider adding diagnostic logging around token acquisition to pinpoint the source of authentication failures.
