c# - 无法使用Azure功能将消息发送到服务总线队列

Question

我有如下所示的 Azure 功能 -

[FunctionName("Demo")]
        public static void Run([ServiceBusTrigger("%Demo-Queue%", Connection = "AzureWebJobsBPGAServiceBus")]string myQueueItem,
             [ServiceBus("%Update-Queue%", Connection = "AzureWebJobsBPGAServiceBus")] ICollector<BrokeredMessage> updateMessage,
            TraceWriter log)
        {
            string query = "SELECT Id FROM MyTable";

            var data = dbs.GetData(query).GetAwaiter().GetResult();

            BrokeredMessage brokeredMessage;
            foreach (var item in data)
            {
                JObject jObject = new JObject(new JProperty("Id", item), new JProperty("MessageId", new Guid(item)));
                brokeredMessage = new BrokeredMessage(jObject.ToString());
                updateMessage.Add(brokeredMessage);
            }
        }

But message going in dead letter queue . why ? Message format is also correct.Any clue ?

如果消息被移动到死信队列，原因可能是 one of these 。死信消息中将会添加两个自定义属性，当它被移至死信队列时(DeadLetterReason 和 DeadLetterErrorDescription)，请尝试读取这些属性以查找原因。
