`undefined (reading 'undefined')` on cypress_runner.js

Current behavior

When running on cypress@9.3.1, there is an issue on cypress_runner.js - Cannot read properties of undefined (reading 'undefined'). It happens on https://github.com/cypress-io/cypress/blob/8355e5d8ec35411a6935687c9c91540dd32cf7f4/packages/driver/src/cy/navigation.ts#L29

This error usually happens on cy.go('back'). Failing tests on Cypress dashboard - https://dashboard.cypress.io/projects/oqk3fk/runs/4680/overview

Desired behavior

No undefined error messages

Test code to reproduce

it(‘should return to previous page’, function () { cy.go(‘back’) })

Cypress Version

Other

No response

@thedoublejay Thank you for posting this… helped me narrow down an issue that was really bothering us. For Cypress team I’d like to point out that this error includes the message “The following error originated from your application code, not from Cypress.” which really lead us astray!!

We have a test that navigate between 2 pages and we assert about keeping some query params in the URL after cy.go(‘back’).

After upgrade cypress this test stoped working. go back seems not working well, sometimes it throws this error, sometimes it does not go back, and rarely it works as it should.

It sounds like the behavior you are describing is a bit unrelated to the original issue. @mr-short put #20948 out to fix the error reported. If this change doesn’t resolve your issues, can you open a new issue with a reproducible example we can use to narrow down the issue you are seeing?
