URL Blocked using Facebook passport auth (React Node.js)-CodePudding

Basically I recently deployed my web app backend to heroku to get the following link:

This is my routes related to the facebook auth

app.get('/auth/facebook',
  passport.authenticate('facebook'));

  app.get('/auth/facebook/callback',
  passport.authenticate('facebook', { failureRedirect: '/login' }),
  function(req, res) {
    // Successful authentication, redirect home.
    res.redirect('http://localhost:3000/home');
  });

On the react front-end, the login button has the following onClick

const facebookLogin = () => {
    window.open("https://crop-disease-backend.herokuapp.com/auth/facebook" , "_self")
  }

Is what I have input in the facebook developer console correct? or something is wrong because I am certain that it has to do with that. Does it also have to do with the fact that my app mode is in development?

CodePudding user response：

I was able to fix it. Basically the uri in the config was "/auth/facebook/callback" and This uri was not included under valid Oauth Redirect URLs so i needed to add that in the valid Oauth Redirect URLs section like so:

https://crop-disease-backend.herokuapp.com/auth/facebook/callback

Now it works like a charm.
