google oauth login error Insufficient Permission

Question

While implementing Google oauth login, there was a problem in retrieving user information.

// socialLoginController.js
  const { code } = req.query;
  const baseUrl = 'https://www.googleapis.com/oauth2/v4/token';
  const urlConfig = {
    client_id: process.env.GOOGLE_CLIENT_ID,
    client_secret: process.env.GOOGLE_CLIENT_SECRET,
    code,
    grant_type: 'authorization_code',
    redirect_uri: 'http://localhost:4000/users/google/oauth',
  };
  const finalUrl = combineUrlAndParams(baseUrl, urlConfig);
  console.log(finalUrl);
  const tokenRequest = await (
    await fetch(finalUrl, {
      method: 'POST',
      headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
      },
    })
  ).json();
  if ('access_token' in tokenRequest) {
    const { access_token } = tokenRequest;
    const userRequest = await (
      await fetch('https://www.googleapis.com/drive/v2/files', {
        headers: {
          Authorization: `Bearer ${access_token}`,
        },
      })
    ).json();
    console.log(userRequest);

At this time, when I checked the userRequest log, the following error appeared.

{
  error: {
    errors: [ [Object] ],
    code: 403,
    message: 'Insufficient Permission: Request had insufficient authentication scopes.'
  }
}

It seems to be a scope problem, so I tried setting the scope to openid, profile, email, or not registering the scope at all, etc., but I keep getting the above error. I don't know what the hell is the problem.
