I believe, all you are missing is: emitsError. BehaviourSubject has a cached value, so how you'd go about testing this is:

how are you compiling this? Based on your syntax and the names of your compiled modules, I'm assuming you're using either Webpack, which means you're likely using Typescript (unless you meant to tag as AngularJS instead). In any case, ES6 import statements are the same, and the syntax you're using is for default exports only.

import can only be used in ES6 JS if type="module" is on the script tag.

Try running browsersync before you minify css:

Solved! The problem is on the loop for on it's condition to running the loop. So I changed my task code to this and now works:
