In my Sveltekit app I have a server.ts file that handles the callback from Github oAuth. I use a token to then try and fetch the users information with:

const githubUserResponse = await fetch('https://api.github.com/user', {
            headers: {
                Accept: 'application/vnd.github.v3+json',
                Authorization: `Bearer ${tokens.accessToken}`,          
            }
         });

This request works perfectly in Postman and returns a valid response that looks like:

{
    "login": "example",
    "id": 000000000,
    "node_id": "U_0000000000",
    "avatar_url": "https://avatars.githubusercontent.com/u/000000000?v=4",
    "gravatar_id": "",
    ...
}

But when I run this code locally in my application I get this response from the cloudflare worker that handles this request in the back end

Response {
  cf: undefined,
  webSocket: null,
  url: 'https://api.github.com/user',
  redirected: false,
  ok: false,
  headers: Headers(8) {
    'cache-control' => 'no-cache',
    'connection' => 'close',
    'content-security-policy' => "default-src 'none'; style-src 'unsafe-inline'",
    'content-type' => 'text/html; charset=utf-8',
    'strict-transport-security' => 'max-age=31536000',
    'x-content-type-options' => 'nosniff',
    'x-frame-options' => 'deny',
    'x-xss-protection' => '0',
    [immutable]: true
  },
  statusText: 'Forbidden',
  status: 403,
  bodyUsed: false,
  body: ReadableStream {
    locked: false,
    [state]: 'readable',
    [supportsBYOB]: true,
    [length]: undefined
  }
}

I don’t know why the request isn’t returning any data and is “forbidden”. Is it not passing along the headers? I am new to this stack. Any help would be appreciated. Thank you!
