Hey Roy Ibarra

There may be some problems with the Fetch header, try adding Content-Type to your fetch request header in src/app/page.tsx, e.g. 'Content-Type': 'application/json', and try again.

  async function sendRequest(url: string, { arg }: { arg: { email: string }}) {
    return fetch(url, {
      headers: {
        'Content-Type': 'application/json'
      },
      method: 'POST',
      body: JSON.stringify(arg)
    }).then(res => res.json())
  }

Thank you for your feedback. I will add a headers and update this part code.

Kevin Wu it worked! Thank you!
