无法使用 Visual Studio Code 创建 Azure 逻辑应用工作流

Question

尝试遵循本教程。

当我右键单击工作流.json 并选择 Open in Designer 时，我终于收到以下消息。

[2021-11-11T16:25:32.880Z] A host error has occurred during startup operation 'ae98f37d-d7d4-4131-920d-a725de7dc6cb'.

我什至使用命令更新了 csproj 文件

dotnet add package Microsoft.Azure.WebJobs.Extensions.EventHubs --version 4.3.0

但问题仍然存在。

另外，正如您所看到的，设计器尝试获取某些内容，但它显示“无法获取”

最后，正如您在图像右下角看到的那样，我收到了这条消息

工作流验证失败：请求 http://localhost:8000/runtime/webhooks/workflow/api/management/workflows/Stateful1/validate?api-version=2019-10-01-edge-preview 失败，原因：连接 ECONNREFUSED 127.0 .0.1:8000。指示的来源是 Azure 逻辑应用（标准）（扩展）

有任何想法吗？

我又找到了一个YouTube 教程，但无法在我的机器上运行。

也在 github 上提出了问题。

我遇到过同样的问题。就我而言，解决方案是进入“控制面板”并卸载 Azure Function Core Tool (4.x)（如果可用）。然后打开 Powershell 并运行以下命令：

npm install -g azure-functions-core-tools@3 --unsafe-perm false
