Bypass login or provide email/pass in url

Help

I’ve been trying this method but I keep getting errors. The latest error is:
code:“bad.connection”
description:“Connection does not exist”

my code is copy/pasted from the example code like this:

function sendEmail() {
var webAuth = new auth0.WebAuth({
domain: ‘app.auth0.com’,
clientID: ‘clientid’,
redirectUri: ‘redirecturl’,
responseType: ‘token id_token’,
});

    var email = $('#email').val();
    console.log('email', email);

    webAuth.passwordlessStart({
      connection: 'email',
      send: 'link',
      email: email,
    }, function (err,res) {
      if (err) {
        console.log(err);
      }

      console.log('done');
    });
  }
