CSS Modules class names undefined

I try to use css modules in my project. I'm using latest Create React App with react-scripts version 2.1.8. In the docs it says I can add CSS Modules, and i dont have to do eject script.

I tried to do the same way, but my styles are empty and classes are undefined. Here is the code for one of my components:

import React, { Component } from 'react';
import styles from './Catalog.css';

class Catalog extends Component{

render() {
    console.log('styles.catalog '+ styles.catalog); //returns: styles.catalog undefined.
    return (
      <div className={styles.catalog}> //returns: <div>
        ...
      </div>
    )
}

Catalog.css:

.catalog {
  min-width: 800px;
}

Adding this answer in case someone else ends up with the same problem as me. My problem was a case sensitivity issue. Apparently the styles still worked when I loaded the file "../inputTextField.scss" when it should have loaded with uppercase I from "./InputTextField.scss"

Somehow it still "cached" the styles or something because the main style worked when doing changes but if I added a style to the component like "style.inverted" and then added that class to the scss file it didn't recognise it and it became undefined.

It's also not recommended to use like catalog-v2.module.css. Instead it'd work if the name of the file is like catalogV2.module.css

In the docs, it's mentioned that you have to name the file as follow :

[name].module.css

Try renaming the file to : Catalog.module.css and import it like this :

import styles from './Catalog.module.css';
