A KEDA Service Bus scaler is configured but the app never scales. Which cause is most likely?
- A The queue has too many messages
- B The scaler's connection secret or managed identity lacks permission to read queue metadata (correct answer)
- C maxReplicas is set too high
- D Ingress is set to internal
Shortcut: KEDA must query the queue's message count. If the connection string secret is wrong or the identity lacks Service Bus Data Receiver / Manage rights, the metric reads zero and no scaling occurs.
