Azure函数本地运行与部署失败：ScmRunFromPackage为空报错求助

问题背景 #

我开发了一个Azure Blob触发的函数应用，逻辑是触发后读取Blob存储文件，处理后输出CSV。之前用func start能正常本地运行，但Azure故障后，现在本地启动就报错**“ScmRunFromPackage is empty”**，触发功能直接关闭；部署到Azure后，主机显示Running，但函数完全不工作。

卡了好几天了，附上项目结构、配置代码和运行日志，求解决。

项目文件结构 #

• 根目录/
  • host.json
  • local.settings.json
  • BlobTriggerFunction/
    • function.json
    • 业务代码文件（如.cs/.js等）

关键配置代码 #

local.settings.json #

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "UseDevelopmentStorage=true",
    "FUNCTIONS_WORKER_RUNTIME": "dotnet" // 根据实际运行时调整
  }
}

host.json #

{
  "version": "2.0",
  "logging": {
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      }
    }
  }
}

Blob触发函数配置（function.json） #

{
  "bindings": [
    {
      "name": "inputBlob",
      "type": "blobTrigger",
      "direction": "in",
      "path": "input-files/{name}",
      "connection": "AzureWebJobsStorage"
    },
    {
      "name": "outputCsv",
      "type": "blob",
      "direction": "out",
      "path": "output-csv/{name}.csv",
      "connection": "AzureWebJobsStorage"
    }
  ]
}

运行日志 #
