How to run an gp service published to ArcGIS Server from ArcGIS Pro SDK?

[Flayner]

I published my tool to ArcGIS Server as a GPServer.
I have tried running the tool using await Geoprocessing.ExecuteToolAsync(), but doesnt not work. I would like to know the correct way to run my tool.
tks

My code:  

string tool_path = @"C:\Data\Tools\agsfile.ags\Mytool/MyScript";

var gpResult = await Geoprocessing.ExecuteToolAsync(tool_path, null);

When I try use "OpenToolDialog", the message below occurs
