Googleapis revokeCredentials does not return result on successful callback

As per the test suite , the callback function passed to revokeCredentials

gets the result object if the operation was successful, which should contain a success

property. However, when I use this snippet:

oauth2client.revokeCredentials(function (error, result) {
  if (error || !result.success) {
    console.error('Failed to revoke credentials!');
    console.error(error || result);
  } else {
    //...
  }
});

      

        
        
        
      

    

I get: TypeError: Cannot read property 'success' of undefined

- am I missing something?
