TypeError: Cannot read properties of null (reading 'getAttribute') on form submit

[martinambrus]

Current behavior

The test fails without any apparent reason - there is no object on page that I'm trying to get attributes for after the form submit. In fact, there is nothing at all being executed after the form submit but the error is still there.

Desired behavior

The mentioned error should not appear and Cypress testing should continue.

Test code to reproduce

function test_checkout() {
  cy.step( 'go to basket' );
  cy.get( '#block-cart .cart-block--summary a' ).click();
  cy.get('#commerce_cart_form-cart-ajax-wrapper table tbody tr').should('be.visible.and.have.length', 1);

  cy.step( 'go to payment and checkout' );
  // the error will happen after the following line:
  cy.get('#commerce_cart_form-cart-ajax-wrapper #edit-actions #edit-checkout').click();
}

// test logic
describe('AkeVino homepage', () => {

  beforeEach(() => {
    cy.visit('https://akevino.sk/');
    cy.step('Do we have a homepage?');
    cy.get('body').should('have.class', 'path-frontpage');
  });

  it('should add new vine into the basket and go to payment and delivery step', () => {
    cy.step( 'adding to basket' );
    cy.get( '.block-views-blockhomepage-products-block-new-wines .views-view-responsive-grid__item:first .button--add-to-cart' ).click();
    cy.get( '.block-views-blockhomepage-products-block-new-wines .views-view-responsive-grid__item:first .button--add-to-cart' ).parent().should('have.class', 'add-to-cart-clicked');
    cy.waitUntil(() => cy.get('.block-views-blockhomepage-products-block-new-wines .views-view-responsive-grid__item:first .button--add-to-cart').should('not.have.class', 'add-to-cart-clicked'));
    cy.get( '#block-cart .cart-block--summary__count' ).should('contain.text', '1');

    test_checkout();
  });
});
