Ionic 2 does not generate scss source maps. "main.css.map" contains "null"

Question

Could you help me understand why Ionic 2 does not generate scss source maps. After the "ion feed" I move to the www / build folder, there is main.css.map, but it contains null instead of the generated source layouts, how to fix it? Has anyone encountered this issue?

You need to expand the sass.config.js file, by default the original mapping for sass is disabled.

Config / sass.config.js:

module.exports = { sourceMap: true, } 

package.json:

 "config": { "ionic_sass": "./config/sass.config.js", },
