我有一个Azure函数（.net 6.0），它从服务总线接收消息。99%的消息处理得很好，但我偶尔会在Application Insights中收到System.OperationCanceledException。
调用堆栈：

System.OperationCanceledException:

调用堆栈（只是我的代码）：

System.OperationCanceledException
Microsoft.Azure.WebJobs.ServiceBus.MessageProcessor.CompleteProcessingMessageAsync
[external code]
Azure.Messaging.ServiceBus.ServiceBusProcessor+<OnProcessMessageAsync>d__104.MoveNext
[external code]
Azure.Messaging.ServiceBus.ReceiverManager+<OnMessageHandler>d__19.MoveNext
[external code]
Azure.Messaging.ServiceBus.ReceiverManager+<ProcessOneMessage>d__15.MoveNext

查看FormattedMessage：它似乎在ProcessMessageCallback上失败了。我查了一下，我能找到的唯一信息是：从传递给订阅的用户processMessage回调中抛出的错误。
失败的方法是：Azure.Messaging.ServiceBus.ServiceBusProcessor+d__104.MoveNext
对我来说，这看起来像是一个服务总线问题，而不是我的代码。我使用的是Microsoft.Azure.WebJobs.Extensions.ServiceBus v5.5.1。
有没有人遇到过这个问题，或者知道如何解决这个问题？
更新：我添加了异常处理，希望能捕获更多信息：

catch (OperationCanceledException ex)
    {
        throw new OperationCanceledException(ex.Message);
    }
    catch (Exception ex)
    {
        throw new ApplicationException(ex.Message);
    }
