Troubleshooting

500 Error on First Request

Cause: RBAC role assignment hasn't propagated to Service Bus data plane. Solution: Wait 30-60 seconds after provisioning, or restart the function app.

"Unauthorized" or "Forbidden" Errors

Cause: Missing UAMI credential settings. Solution: Ensure all three settings are present in app configuration:

• ServiceBusConnection__fullyQualifiedNamespace
• ServiceBusConnection__credential (value: managedidentity)
• ServiceBusConnection__clientId

See Service Bus trigger connections for identity-based config — refer to the "Connections" section on that page for managed identity app settings.
