Azure 函数 - 无法为运行时启动新的语言工作者：dotnet-isolated

Question

我有一个 dotnet 5 函数应用程序，我已经从 devops 管道构建和部署了几周。

在最新版本之后，我在 App Insights 中看到以下错误：

异常类型 System.TimeoutException 异常消息 操作已超时。 日志级别错误 prop__{OriginalFormat} 无法为运行时启动新的语言工作者：dotnet-isolated。 类别 Microsoft.Azure.WebJobs.Script.Workers.Rpc.RpcFunctionInvocationDispatcher System.TimeoutException：操作已超时。 在 Microsoft.Azure.WebJobs.Script.Grpc.GrpcWorkerChannel.StartWorkerProcessAsync()

host.json：

{
  "version": "2.0"
}

功能应用配置：

[
  {
    "name": "APPINSIGHTS_INSTRUMENTATIONKEY",
    "value": "<my key is here>",
    "slotSetting": true
  },
  {
    "name": "AzureWebJobsStorage",

    "slotSetting": false
  },
  {
    "name": "WEBSITE_RUN_FROM_PACKAGE",
    "value": "1",
    "slotSetting": false
  }
]

函数定义

[Function("HttpExample")]
    public static HttpResponseData Run([HttpTrigger(AuthorizationLevel.Function, "get", "post")] HttpRequestData req,
        FunctionContext executionContext)
    {
        var response = req.CreateResponse(HttpStatusCode.OK);
        response.Headers.Add("Content-Type", "text/plain; charset=utf-8");

        response.WriteString("Welcome to Azure Functions!");

        return response;
    }

还有其他人遇到过这个问题吗？

注意：我现在已经通过 Azure 门户为此创建了一个支持票证 - ID 是 2106280050000196。Github 问题here

编辑： 根据@Kaylan 的建议，我使用 Azure CLI 创建了一个带有 --runtime dotnet-isolated 参数的新函数应用程序。然后我将我的函数部署到其中（使用带有 Deploy Azure Function 任务的 devops 管道），但恐怕我会继续看到同样的错误。

我也尝试部署到固定应用服务计划（而不是消费），但仍然遇到同样的问题。

Answer 1

请对您的 host.json 文件进行以下更改以包含 extensionBundle

{
  "version": "2.0",
    "extensionBundle": {
      "id": "Microsoft.Azure.Functions.ExtensionBundle",
      "version": "[2.*, 3.0.0)"
    }
  }
}

升级到 Microsoft.Azure.Functions.Worker 1.3.0 或更高版本

Install-Package Microsoft.Azure.Functions.Worker -Version 1.3.0

确保在创建函数应用程序时指定了适当的运行时。

az functionapp create --consumption-plan-location westus --name <FunctionAppName> --resource-group <ResourceGroupName> --runtime dotnet-isolated --runtime-version 5.0 --functions-version 3 --storage-account <StorageAccountName>

Answer 2

我刚刚运行了 NuGet 包更新：

• Microsoft.Azure.Functions.Worker v1.3.0 → v1.4.0
• Microsoft.Azure.Functions.Worker.sdk v1.0.3 → v1.0.4

这似乎解决了问题。

Answer 3

我遇到了这个问题，因为我已经从一个“普通”的 dotnet 服务转移，需要将 FUNCTIONS_WORKER_RUNTIME 从 dotnet 调整为 dotnet-isolated：

local.settings.json

{
  "IsEncrypted": false,
  "Values": {

    "FUNCTIONS_WORKER_RUNTIME": "dotnet-isolated",
    ....

  }
}
