Upload files for debug

How can I upload the files for debuging errors on a React application? It’s using webpack for building the files and every error looks like this:

I tried to add the sentry plugin for webpack on the build process and I can see all the files on the artifact session on the dashboard but the errors are still unreadable.

This is my webpack plugin configuration:

new SentryCliPlugin({
  release: packageJson.version,
  include: '.',
  ignore: ['node_modules'],
  configFile: 'sentry.properties',
