Trying to build a custom config file that pareses the sitemap xml of the site for a list of paths

im getting `TypeError: Cannot set properties of undefined (setting 'tempCompareConfigFileName')` when I set in the config file `module.exports = getPaths();` within that function im attempting to build the config properties `scenerios` being an array that gets paths push into through a for loop above before returning.

`return {
