findAll promise warning

What are you doing?

module.exports = {
  async getSeries(req, res) {
    const limit = req.swagger.params.limit.value || 5;
    const offset = req.swagger.params.offset.value || 0;
    const allSeries = await series
      .findAll({
        limit,
        offset,
      });
    res.json(allSeries);
  },
};

The query works, there are no errors.

What do you expect to happen?

No warnings.

What is actually happening?

Warning:

(node:21938) Warning: a promise was created in a handler at domain.js:126:23 but was not returned from it, see http://goo.gl/rRqMUw
    at Function.Promise.cast (/a/project/node_modules/bluebird/js/release/promise.js:196:13)

Output, either JSON or SQL

Everything works. Just want to get rid of the warning.

Hi @papb Sorry for late response, i was struggling with the warning to come up into the terminal. Setting the NODE_ENV=development was the missing link.

Demonstrating the warning can be found here. I added it as a pull-request. I only configured the NODE_ENV for the travis ci, so for now you can see the warnings here.

I didn’t added the NODE_ENV thats why appvoyer ci, that is why log did not shows the warning.

I’m also getting this warning while running in NODE_ENV=development mode.

Bluebird doc confirms that setting the NODE_ENV=development mode, enables BLUEBIRD_WARNINGS

Both features are automatically enabled if the BLUEBIRD_DEBUG environment variable has been set or if the NODE_ENV environment variable is equal to “development”.

Yes, I also find this warning occured when i set NODE_ENV=development with version 5.21.5 Its bluebirds problem.
