I like this addition, I'd way rather the library fail early than run in an undefined state with no project ID.

if (!projectId) {
throw new Error(
'Unable to detect a Project Id in the current environment. \n' +
'To learn more about authentication and Google APIs, visit: \n' +
'https://cloud.google.com/docs/authentication/getting-started');
}
resolve(projectId);
} catch (e) {
reject(e);
}
});
}
return this._getDefaultProjectIdPromise;
}
