Your code example that you say doesn’t work uses curly quotes, which are not valid characters for JS code (they are valid in strings, but not to demarcate a string literal). It may be just an artefact of the way you’ve cut and pasted your code example here. Nonetheless, ensure your config.js file uses straight single and double inverted commas.
