Can't authorize through auth0 in a backstage app by using Cypress and auth0 simulation

For some reason, the authorization through auth0 simulation doesn't work in tests with Cypress.

We tried to investigate it and used different suggestions to find the source of the problem. I don't know well auth0, so @dagda1 could you please correct me if said something wrong.

From all discussions, I noticed that there are a couple of possible sources of that problem:

• The backstage using some old way to authorize by opening a new window instead of creating an iframe
• Cypress uses its own SSL certificate, so the token couldn't be set

@wKich it is very weird. we've used it in other repos that did not use the new window approach without these problems.

the new window seems to be causing problems. i think in general we need lots of logging throughout simulacrum that you can turn off and on so we can debug easier.

i have a pr PR that logs each express request
