Publishing new project created to group share

I am failing to publish a newly created project to group share.

The code snippet is:

newProject.PublishProject(
new Uri("http://testing.corp.com:80"),
false,
"abc",
"abc",
"/Portuguese",
new EventHandler<PublishProjectEventArgs>(this.Publish));

The event handler give me the msg scheduling but no error msg when and why it fails.

Can somebody help me identify the issue. thanks
