c# - Microsoft.Azure.ServiceBus : The lock supplied is invalid. 锁定已过期，或者消息已从队列中删除

Question

我有一个服务总线主题触发函数，只要将某些数据推送到主题，该函数就会被触发。

函数看起来像这样:

[FunctionName("funcGetServiceBusEntities")]
public async Task Run([ServiceBusTrigger("sbtopic", "sbsub", Connection = "ServiceBusConnectionString")]Message message, MessageReceiver messageReceiver, [DurableClient] IDurableOrchestrationClient starter, ILogger log)
{  
   // perform processing on the data

   //...

   //...

   // Complete since we don't want to process the message again
   await messageReceiver.CompleteAsync(message.SystemProperties.LockToken);

   //...
}

我不确定为什么会出现此错误:

Microsoft.Azure.ServiceBus: The lock supplied is invalid. Either the lock expired, or the message has already been removed from the queue.

CompleteAsync 的实现有错吗？

这就是你现在面临的情况:

请注意，触发后消息将被删除。所以你不需要标记它，也不用担心再次处理消息。它已被删除。
