ReactJS: Unable to show code from C file which I fetch from rawgithub

I use the following code to fetch the C language files from RawGithub it works for other languages but in C it shows the HTML of my react app

const [code, setCode] = useState("");
useEffect(() => {
    fetch(codeRawUrl, {
      headers: {
          'Content-Type': 'text/plain'
        }
      })
      .then((response) => response.text())
      .then((text) => setCode(text));
  }, [codeRawUrl]);

 <code className={`language-${language} match-braces rainbow-braces`}>
    {code}
 </code>
