如何从另一个模块在物联网边缘代理上调用直接方法？

我正在试用1.0.10-rc2中的实验功能。

edgeAgent UploadModuleLogs上有直接方法。

我可以从Azure门户调用该方法，并且效果很好。我正在尝试像这样在同一设备上的模块中调用该方法：

static async Task Init()
{
...

  await ioTHubModuleClient.SetMethodHandlerAsync("UploadModuleLogs", UploadModuleLogs, ioTHubModuleClient);
}

private static async Task<MethodResponse> UploadModuleLogs(MethodRequest methodRequest, object userContext)
{
  ModuleClient ioTHubModuleClient = (ModuleClient)userContext;

  // Upload logs
  Console.WriteLine("Invoking method On edgeAgent");

  var payload = @"{
""schemaVersion"": ""1.0"",
""sasUrl"": ""https://..."",
""items"": [
    {
        ""id"": "".*"", 
        ""filter"": {
            ""tail"": 100
        }
    }
],
""encoding"": ""none"", 
""contentType"": ""text""
} ";

  MethodRequest request = new MethodRequest("UploadModuleLogs", Encoding.UTF8.GetBytes(payload));

  string myModuleId = Environment.GetEnvironmentVariable("IOTEDGE_MODULEID");
  string myDeviceId = Environment.GetEnvironmentVariable("IOTEDGE_DEVICEID");

  Console.WriteLine($"{myDeviceId} {myModuleId} - UploadModuleLogs method request at {DateTime.Now}");
  //Console.WriteLine($"{request.DataAsJson}");

  try
  {
    var response = await ioTHubModuleClient.InvokeMethodAsync(myDeviceId, "$edgeAgent", request).ConfigureAwait(false);
    Console.WriteLine($"Received response with status: {response.Status} with message: {response.ResultAsJson}");

    return response;
  }
  catch (Exception ex)
  {
    Console.WriteLine($"Error invoking method {ex}");
  }

  return null;

尝试运行此：
