Code not explicit where the login redirect url is

[m4v15]

  handler: (request, reply) => {
    const params = {
      client_id: process.env.CLIENT_ID
    };
    reply.redirect(`https://github.com/login/oauth/authorize?${qs.stringify(params)}`);
  }

I know you don't need to say what the redirect url is as when you registered your app you gave github a redirect url, but as a code reviewer I don't know where this will redirect me.
