Using cy.route2, unable to find alias when running in CI (Github actions)

[ChrisSargent]

Current behavior

I have some tests that are passing using open and when using run on my local machine, but which are failing in a Github action. Error is CypressError: cy.wait() could not find a registered alias for: ....

Desired behavior

The aliased routes in the beforeEach should be available (note they are correctly available in previous and later tests)

Test code to reproduce

Minimal setup is here: https://github.com/ChrisSargent/cypress-test-tiny.

Versions

Cypress 5.5.0

Actually, I now have this happening in my local machine so at least I can start troubleshooting a little bit easier. Moving the route2 call to a test specific beforeEach instead of a beforeEach in the commands.js file seemed to get passed this error, but then I started getting undefined for the request - I have a feeling this is something to do with network requests being cancelled from the previous test, because if I skip the previous tests or just stick in a cy.wait(1000) at the end, the following tests pass okay (and I mean previous test in a different describe block)

Okay, now running locally in Electron but with the --headed option, I can see I get a Cypress error as above:

> Cannot access 'continueSent' before initialization

Seems that it would be related to this: #8926, just strange that it works fine when using cypress open vs run

[ChrisSargent]

Sorry for the running commentary, but... okay, I moved all my route2 setup out of the beforeEach in to a setupRoutes function that I call at the beginning of each test, before cy.visit. I still get the same error which results in the request being undefined in the subsequent wait. Seems rather flaky because sometimes it's working, sometimes it's not. Works less often when the tests are running headlessly.

Adding cy.wait(1000); to my previous test to get passed this for now and waiting for this fix before investigating further: #8978

I think you're running into this issue - which is a timing issue, so it makes sense that it may only happen during cypress run - since there could be some variability in the way it runs in Electron versus Chrome or on your GitHub action versus locally.
