title: Google Developers Console - Error when inviting user to project
body: <p>I have a new project in the developers console, and cannot seem to add new users. I send the invitation, this is forwarded to the correct Gmail account with the RSVP link:</p>
  
  <p>'<a href="https://console.developers.google.com/project/[appname]/rsvp/" rel="nofollow">https://console.developers.google.com/project/[appname]/rsvp/</a>'</p>
  
  <p>which however results in an error message:</p>
  
  <p>'The server has encountered a problem. Please try again.'</p>
  
  <p>We tried inviting other gmail users and still no luck.</p>
  
  <p>We also made this user an administrator of the billing account, and that works fine. Just the project is not visible to the user.</p>
  
  <p>Anyone has an idea what could be the problem?</p>
  
  <p>Thanks!</p>
