Azure函数:HttpTrigger和输出队列返回“内部服务器错误”

我有以下功能代码:

public static class FunctionCheckEmail
{
    [FunctionName("FunctionCheckEmail")]
    public static IActionResult Run(
        [HttpTrigger(AuthorizationLevel.Function, "post", Route = null)] HttpRequest req,
        [Queue("email-message-admin-confirmation", Connection = "StorageConnectionString")]CloudQueue outputQueue,
        ExecutionContext context,
        ILogger log)
    {
        log.LogInformation("C# HTTP trigger function processed a request.");
        return new AcceptedResult();
    }
}

Internal Server Error .

如果我删除队列绑定,那么它可以工作:

public static class FunctionCheckEmail
{
    [FunctionName("FunctionCheckEmail")]
    public static IActionResult Run(
        [HttpTrigger(AuthorizationLevel.Function, "post", Route = null)] HttpRequest req,
        ExecutionContext context,
        ILogger log)
    {
        log.LogInformation("C# HTTP trigger function processed a request.");
        return new AcceptedResult();
    }
}

其他带有队列绑定的函数可以正常工作:

public static class FunctionWarningNotification
{
    [FunctionName("FunctionWarningNotification")]
    public static void Run(
        [QueueTrigger("emails-warning-notification", Connection = "StorageConnectionString")]string myQueueItem,
        [SendGrid] out SendGridMessage message,
        ExecutionContext context,
        ILogger log)
    {
        //....
    }
}

主机.json:

{
  "version": "2.0",
  "extensions": {}
}

local.settings.json文件:
