运行Azure Event Hub触发器函数本地报错：unexpected status code: 400

我在VS Code中本地运行Azure Event Hub触发器的基础模板函数，代码如下：

import logging

import azure.functions as func


def main(event: func.EventHubEvent):
    logging.info('Python EventHub trigger processed an event: %s',
                 event.get_body().decode('utf-8'))

执行时出现unexpected status code: 400错误。本地Functions服务已正常运行，且已确认function.json中的Event Hub实例名称正确：

{
  "scriptFile": "__init__.py",
  "bindings": [
    {
      "type": "eventHubTrigger",
      "name": "event",
      "direction": "in",
      "eventHubName": "homeeventhub",
      "connection": "",
      "cardinality": "many",
      "consumerGroup": "$Default"
    }
  ]
}

完整错误日志如下：

我认为这是本地配置问题，但不知道还需要排查哪些项。我另有一个HTTP函数可正常本地运行，请问还有哪些配置需要设置？
