Getting "Not authorized to access the application ID" in Google Apps Marketplace API

I'm trying to list all domain installations of my application.

For this I:

• Published my application privately for the domain;
• Enabled both Google Apps Marketplace API and Apps Marketplace SDK for my project;
• Configured Apps Marketplace SDK (added scope: "https://www.googleapis.com/auth/appsmarketplace.license");
• Created a service account with the following roles: Project Owner, Project Editor;
• Tried to access API from Java with correctly scoped credentials and failed.

All the time I get the same 403 error:

{
    "error": {
         "errors":[{
             "domain": "global",
             "reason": "forbidden",
             "message": "Not authorized to access the application ID"
         }],
         "code":403,"message":"Not authorized to access the application ID"
    }
}

Could any one explain what do I miss here?

I've added to more roles: Project Browser and Project Viewer. Either one of them or they both seems to have fixed the problem.
