带有ServiceBus的Azure功能：操作已取消

我刚刚为Azure功能部署了一个更新：计时器或servicebus触发器具有不同的功能。最近几天我发现与ServiceBus相关的错误

Microsoft.Azure.ServiceBus.ServiceBusCommunicationException-操作已取消。

enter image description here

我不知道函数接收消息时是否正在发生这种情况？

函数定义如下

[FunctionName("createInvoiceListFromServiceBus")]
public async Task Run(
        [ServiceBusTrigger("invoice.requests.bulk", "requests", Connection = "AccountingServiceBusConnection")] 
        string myQueueItem,
        [ServiceBus("invoice.pdf.requests", Connection = "AccountingServiceBusConnection")] 
        IAsyncCollector<dynamic> pdfServiceBusRequests,
        [ServiceBus("invoice.paid.requests", Connection = "AccountingServiceBusConnection")] 
        IAsyncCollector<dynamic> paidServiceBusRequests)
    {
    }

这是我正在使用的软件包

<PackageReference Include="AzureExtensions.Swashbuckle" Version="3.2.2" />
<PackageReference Include="Microsoft.Azure.Functions.Extensions" Version="1.0.0" />
<PackageReference Include="Microsoft.Azure.KeyVault.Core" Version="3.0.5" />
<PackageReference Include="Microsoft.Azure.Storage.Blob" Version="11.1.7" />
<PackageReference Include="Microsoft.Azure.WebJobs.Extensions.ServiceBus" Version="4.1.2" />
<PackageReference Include="Microsoft.EntityFrameworkCore" Version="3.1.4" />

<PackageReference Include="Microsoft.NET.Sdk.Functions" Version="3.0.7" />
<PackageReference Include="Xero.Api.SDK.Core" Version="1.1.4" />

这里是完整的错误描述。

错误是暂时的吗？然后，很可能是应用程序与其依赖项之间的某种连接问题。错误The operation was canceled表示一个异步任务已被取消，或者很可能超时。
https://www.asptricks.net/2019/10/task-cancellationtoken-net-c-example.html

要进行超时搜索...查看pasredStack似乎是使用Microsoft.Azure.ServiceBus.Core.MessageReceiver超时的代码。从主要的主要run()方法可以推断出使用AccountingServiceBusConnection的两个操作之一可能已超时。

为重现该错误，我建议尝试在同时负载测试以下基础资源：pdfServiceBusRequests和paidServiceBusRequests的同时尝试此操作

或者，您可以延长某些隐式超时时间。考虑一下这些服务。有什么可能会超时吗？我们使用的是http客户端还是sql客户端？这些客户端倾向于具有隐式的默认超时，可以在代码中覆盖这些超时。我建议搜寻任何引用来进行Web或数据库调用的客户端，并搜索将其超时扩展到最大，以缓解此问题。另一个选择可能是尝试捕获并处理这些System.OperationCanceledException正常情况。
