After the upgrade to Chrome 71, Cypress is throwing a cross-origin frame error (image below). If I downgrade my Chrome to 70 or run the tests with the Electron version, the tests run.

Could you provide your test code please? We will need a way to reproduce this on our side in order to investigate it.
@jennifer-shehane it breaks on cy.visit('/'), the spec's first lines.
In my codebase, I have an interceptor that if the user is not logged in, I redirect him to /#/login. If he is logged, he will be redirected to /#/dashboard. It is the beginning of the test, so the user is not logged in yet and he will be redirected to login page. Here, the Cypress breaks.
If in my tests I set the cy.visit to /#/login, the Cypress does not break.
I'll try to post a very simple example with that as soon as possible.
I have tested this error on 3.1.2 and 3.1.3 Cypress versions, both break on Chrome 71. It pass on Chrome 70 or earlier.
Thank you.
edit1: some misspellings.
edit2: info about versions.
I just upgraded from 3.1.1 to 3.1.3 and I experienced this same issue. I tried following the steps on https://github.com/cypress-io/cypress/issues/1239 by deleting the app data and restarting it but it didn't work for me :( . I was trying to run Cypress > integration > examples > action.spec.js file
Happening with me in 3.1.4
Unfortunately we'll have to close this issue if no reproducible example is provided. Can anyone provide a way to reproduce this?
My STR:
Initial:
No chrome installed.
No Cypress installed.
cypress openIn the Test Runner, instead choosing Electron 59, I chose Chrome 71.

Run any test

But if the test is run on Electron 59, it's okay.
Unfortunately we have to close this issue as there is not enough information to reproduce the problem - following the steps provided does not cause the error shown for us.
Please comment in this issue with a reproducible example and we will reopen the issue. 馃檹
Anyone know how to solve this problem?
