Workaround idea: Clear cookies in an intercepted request

cypress-io/cypress#25841 (comment)

In our case, after the button is clicked, there are two consecutive requests. The first request will respond with a new cookie value, set-cookie, and then the new cookie value will be used in the second request. When seeing the networking tab in dev tools, the browser displays the correct cookies to be sent; however, with debug in Cypress, it does send the old cookies from the cookie jar. I found a temporary workaround in our case, which is deleting cookies after sending the first request and before getting the response with a new cookie value. In this case, Cypress is using cookies from the request header since the jar is empty. I still wonder what the method that updates or syncs the cookie jar value in the Cypress code since the browser cookie jar is correct.

Here the temporary workaround I am currently using: cy.intercept('POST', 'endpoint').as('firstRequest'); cy.get('body').find('button[type="button"]').contains('login').click(); cy.wait('@firstRequest').then((interception) => { // Delete all cookies after sending the request cy.clearCookies(); }); @valscion

However, the workaround seems to require clicking the button triggering the fetch request twice so it is not a satisfiable workaround.
