How to get info back from facebook login?

[RonAlmog]

working on the facebook login, no luck yet.
my backend is nestjs, following the tutorial here.
in the facebook setting i entered the 'site url' as http://localhost:3000/api/auth/facebook/redirect,
which is on the backend. (is this correct? not sure)
my nuxt config:

facebook: {
        scheme: 'oauth2',
        endpoints: {
          authorization: `${process.env.API_URL}/auth/facebook`,
          userInfo: `${process.env.API_URL}/auth/user`,
        },
        scope: ['public_profile', 'email'],
        responseType: 'token id_token',
        token: {
          property: 'access_token',
          type: 'Bearer',
          maxAge: 1800,
        },
      },

now when click the facebook login on the nuxt website, it goes to facebook, asking for permission, and then going to the redirect path and what i get in browser is like this:

what am i doing wrong here?
