Errors Solutions

The following error originated from your application code, not from Cypress. It was caused by an unhandled promise rejection.

Solución:

Add in the support/index.js file:

import './commands'
Cypress.on('uncaught:exception', (err, runnable) => {
  // returning false here prevents Cypress from failing the test
  return false
})
