The import path /src/* maybe is wrong. I may need more info, but if this file you've shown is inside the src folder then the import path is incorrect. To be explicit, you need a relative path to any .css files.

Now I may be mistaken, but the js imports need to be named. I can see you're using TypeScript and you're using import statements, so I am only guessing but you'll need to name the import or import the specific "thing" you export in the js files. This can look like the following:

import fit from "/src/assets/js/*";

or

import { fit } from "/src/assets/js/*";

and the export in the custom.min.js file should look like:

export default fit;

or

export { fit };

Now for your .css and .js, if this is your directory:

__src
  |___ assets
  |
  |___ components
  |
  |
  |___ App.tsx
  |___ App.css
  |___ ...(everything else that lives in `src/` from a `create-react-app`)

then you will need to import the .css file like so into the App.tsx:

import "./assets/style/style.css"

You can optionally leave out the extension, but I am not 100% sure for .css files.

Hope this helps!

In case you're trying to use an absolute path for your imports, you need to remove the backslash before the 'src'.

In your case, the imports are prefixed with '/' so it looks for the 'src' folder inside the current directory, 'src/components/organisms/sidebar/src/{your imports}'.

Choosing between relative and absolute imports is a matter of a personal opinion as they both have trade-offs, this will make it clearer, and this.
