Error al utilizar ServiceBusProcessor – SDK de Azure.Messaging.ServiceBus

Estoy recibiendo una excepción después del método StartProcessingAsync(). El puntero de depuración va al método “ProcessorErrorAsync”. Seguí pasos similares proporcionados en el enlace – https://github.com/Azure/azure-sdk-for-net/blob/main/sdk/servicebus/Azure.Messaging.ServiceBus/samples/Sample04_Processor.md
¿Me estoy saltando algún paso aquí?
Detalles de la excepción: error.Exception.Message:
