import { Homepage } from "../pages/Homepage"

 
const homepage = new Homepage();

console.log(homepage)

describe('empty spec', () => {
    beforeEach("visit google", ()=>{
      homepage.navigate();
        cy.viewport(1920, 1080)

    })


    
    
it.only('Check Distance dropdown is working ', () => {

const login = homepage.facebookLogin();
})

})

/// <reference types="Cypress" />


export class Homepage {                 
  navigate() {                              //This function will lead to homePage -> SELECT LOCATION
      cy.on('uncaught:exception', (err, runnable) => {
          return false
      })
      cy.viewport(1920, 1080) 
       
      cy.visit(Cypress.env('host'));
      cy.viewport(1920, 1080) 
      // cy.get(':nth-child(2) > .img-icon-nav').click()
      cy.get(':nth-child(3) > .top-menu-item').click()
  }

facebookLogin(){

  const username = Cypress.env('facebookSocialLoginUsername')
  const password = Cypress.env('facebookSocialLoginPassword')
  const loginUrl = Cypress.env('facebookLoginUrl')
  const cookieName = Cypress.env('qattCookieName')
  const socialLoginOptions = {
    username: username,

  }
  cy.clearCookies()
  return cy.task('FacebookSocialLogin', socialLoginOptions).then(results => {
    results['cookies'].forEach(cookie => {
      if (cookie.domain.includes(cookieName)) {
        cy.setCookie(cookie.name, cookie.value, {
          domain: cookie.domain,
          expiry: cookie.expires,
          httpOnly: cookie.httpOnly,
          path: cookie.path,
          secure: cookie.secure

      }
    })
    cy.window().then(window => {
      Object.keys(results.ssd).forEach(key => window.sessionStorage.setItem(key, results.ssd[key]))
      Object.keys(results.lsd).forEach(key => window.localStorage.setItem(key, results.lsd[key]))
    })
  })
}

I am trying to automate third-party login (0auth) of Facebook on a site. I have faced an issue when cypress types email and password and clicks login. But the Facebook page not redirecting to the home page.
