Remove relation throws exception

[cychiuae]

Follow the example in Skygear JS SDK documentation.

const unFollow = new skygear.relation.Follower([ben]);
skygear.relation.remove(unFollow).then((result) => {
  console.log(result.success); // Return an array of user, here is [ben]
}, (error) => {
  console.error(error);
});

It will throw an exception, TypeError: Cannot read property 'user_id' of undefined.

This exception is due to the fact that JS SDK expects Skygear server returns a list of users whose relation is successfully removed in result.data. However, the server does not return that field currently.

• Skygear SDK Date/Version: 0.17.0
• Skygear Server Date/Version: 0.17.0

Expected Results

No exception when removing a relation

Actual Results

Throw an exeception
