	const [user, repo] = urlPieces.slice(0, 2);
	// TODO(davideast): Don't hardcode main branch

to use latest node-fetch version you would need to use import instead of require

 async function fetchCode(githubPath) { 
   const fetch = globalThis.fetch || import('node-fetch').then(mod => mod.default);
   const githubApiUrl = convertToGitHubApiUrl(githubPath); 
   const response = await fetch(githubApiUrl); 
   return response.text(); 
 }
