Стамбульский отчет не может найти исходные карты

Question

При попытке создать отчет в Стамбуле (приложение angular2-cli) я получаю следующую ошибку

[Error: Could not find source map for:"/Users/dylan/IdeaProjects/IssueTracker2-UI/code/dist/vendor/es6-shim/es6-shim.js"]
[Error: Could not find source map for: "/Users/dylan/IdeaProjects/IssueTracker2-UI/code/dist/vendor/zone.js/dist/zone.js"]
Error: Could not find file: "/Users/dylan/IdeaProjects/IssueTracker2-UI/code/dist/vendor/systemjs/dist/system-polyfills.js.map"

Это когда я бегу npm run posttest, Это отмечено в моем package.json в следующем.

     "posttest": "node_modules/.bin/remap-istanbul -i coverage/coverage-final.json -o coverage -t html",
     "coverage": "http-server -c-1 -o -p 9875 ./coverage"

Ниже я покажу свой karma.conf.js файл

 // Karma configuration file, see link for more information
// https://karma-runner.github.io/0.13/config/configuration-file.html

module.exports = function (config) {
config.set({

};

Спасибо!
