javascript - Ufanget SyntaxError: Uventet token '<' i React-app

Jeg har et problem med React-appen. Ved oppstart av applikasjonen får jeg en feil som nedenfor i Chrome-konsollen:

Jeg har ingen idé hvorfor, jeg går gjennom nesten hvert emne med denne feilen, men ingenting hjelper meg. Dette er koden min:

Jeg ville prøvd å manuelt skrive inn %YOUR_URL%/bundle.js i nettleseren din.

Sannsynligheten er at serveren sender deg en 404 HTML-side i stedet for den forventede JS-bunten.
