a promise was created in a handler but was not returned from it

Hello,

I am trying to use Koa with MongooseJS.

here is the MongooseJS code

export function* update(next) {
  this.response.body = yield Item
    .findById(this.params.id).exec()
    .then(item => {
      const updated = _.merge(item, this.request.body);
      return updated.save();
    });
}

Seems like I’m missing something obvious but I don’t know what is it.

This is new bluebird feature (mongoose is using it). http://bluebirdjs.com/docs/warning-explanations.html#warning-a-promise-was-created-in-a-handler-but-none-were-returned-from-it It means that something is broken in mongoose. It shows up only when you use then and have BLUEBIRD_DEBUG=1 or NODE_ENV=development in your env.
