Failed to parse source map, React package

I'm using this package in a React application set up with create-react-app. When I import the slider with

import { ImgComparisonSlider } from "@img-comparison-slider/react";

It causes an error

Failed to parse source map from '/Users/roman/Documents/img-comparison-slider-test/node_modules/@img-comparison-slider/react/src/index.tsx' file: Error: ENOENT: no such file or directory, open '/Users/roman/Documents/img-comparison-slider-test/node_modules/@img-comparison-slider/react/src/index.tsx'

This doesn't really affect the application, but having the warning is annoying. As a workaround, I can do something like this:

import "img-comparison-slider";

<img-comparison-slider>
  <img slot="first" src={srcFirst} alt="" />
  <img slot="second" src={srcSecond} alt="" />
</img-comparison-slider>

But I can't style the slider with styled-components or emotion in this case. Unfortunately, disabling source maps is not an option.
