在 Visual Studio Code 上调试 Azure 函数时出错（“LogType”不存在）

Question

我在 Visual Studio Code 上使用 Python 3.7.3。

使用 BlobTrigger 在本地调试一个非常简单的 Azure 函数会引发错误

An unhandled exception has occurred. Host is shutting down.
System.Private.CoreLib: The given key 'LogType' was not present in the dictionary.

该函数只是 VS Code 在使用 BlobTrigger 设置函数时给出的默认值（见下文）

import logging

import azure.functions as func


def main(myblob: func.InputStream):
    logging.info(f"Python blob trigger function processed blob \n"
                 f"Name: {myblob.name}\n"
                 f"Blob Size: {myblob.length} bytes")

终端的输出如下：

> Executing task: venv\Scripts\python -m pip install -r requirements.txt <

Requirement already satisfied: azure-functions==1.0.5 in d:\epiq\code\functions\blob_trigger_add\venv\lib\site-packages (from -r requirements.txt (line 1)) (1.0.5)

> Executing task: venv\Scripts\activate ; func host start <

Found Python version 3.7.3 (python).

关于如何解决问题的任何想法？

Answer 1

在 host.json 文件中更改此内容：

{
   "version": "2.0",
   "extensionBundle": {
     "id": "Microsoft.Azure.Functions.ExtensionBundle",
     "version": "[1.*, 2.0.0)"
   }
}

对此：

{
   "version": "2.0",
}

它对我有用，也许对你有用。 或者您是否设法以另一种方式解决了这个问题？
