输出到ServiceBus的Azure函数收到绑定错误

Question

  

System.Private.CoreLib：执行函数X时发生异常。
  Microsoft.Azure.WebJobs.Host：异常绑定参数   'outputQueue'。
System.Private.Uri：值不能为null。
参数   名称：uriString

我班上的标题如下

[FunctionName("MyFunc")]
  public static async  Task<IAsyncCollector<string>> 
    Run(
      [HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = null)] 
      HttpRequest req, ILogger log, 
      [ServiceBus("my_queue", EntityType.Queue,Connection = "SLQueueConnectionString")] 
      IAsyncCollector<string> outputQueue
    )

我的local.settings.json

    "Values": {
