Returning asynchronous response in sails.js

My app needs to return a JSON response after some DB queries.

Pseudocode (using async):

async.forEachOf(sails.config.site.regions, function (regionData, slug) {
        obj['regions'][slug] = {
            'slug': slug,
            'name': regionData.name,
        };
    }, function (err) {
        if (err) {
            res.json({
                'error': true,
                'message': 'Error when retrieving data from the DB'
            });
        }
        else {
            res.json(obj);
            return;
        }
    });

Sails hangs since no response seems to be returned from the service.

I tried converting this to a Promise (see this answer) but it doesn't work either.

How can I do this?

Have you tried

async.forEachOf(sails.config.site.regions, function (regionData, slug) {
        obj['regions'][slug] = {
            'slug': slug,
            'name': regionData.name,
        };
    }, function (err) {
        if (err) {
            return res.json({
                'error': true,
                'message': 'Error when retrieving data from the DB'
            });
        }
        else {
            return res.json(obj);

        }
    });
