Hi, I faced the unknown issue with the visiting the localhost of certain project. After this messages it redirects me to the new tab with the login page The problem is that it is open in a new tab and can not be worked with out of the cypress page

The solution depends on how the redirect is implemented. You may need to

cy.stub

a function or

cy.intercept

if it's an HTTP call. Here is a tip in the Cypress docs: https://docs.cypress.io/faq/questions/using-cypress-faq#How-do-I-prevent-application-redirecting-to-another-URL

Maybe you can address the uncaught exception? https://docs.cypress.io/api/events/catalog-of-events#Uncaught-Exceptions
