Can't pass saml authentication on newer Cypress versions

[vintagefuture]

I'm using Cypress 8.7.0 for integration tests on my React application.

The first step for each test is to login to a saml portal, which generates the session cookie.

If I try to upgrade to any version after 8.7.0, either 9.0.0 or even the latest 14.2.1, the authentication fails.

Evertyhing works fine from normal browsers so it must be a specific Cypress thing that changed after 8.7.0.

I initially thought it was a matter of using this workaround https://www.tomoliver.net/posts/cypress-samesite-problem which I did, however the issue continues.

Attached a screenshot of the network tab from normal browser, and from cypress Electron.

What am I missing?

Thanks!!
