@jmsansan Thanks for signing the CLA, unfortunately the author of all of the commits does not match the email address on your GitHub account. There are 2 commits, one made by Jose Sanchez the other made by jmsansan. https://github.com/cypress-io/cypress/pull/7960/commits

Our CLA bot gets confused when they don't match. Here are some solutions to fixing when commits are linked to another wrong user: https://help.github.com/articles/why-are-my-commits-linked-to-the-wrong-user/

@jennifer-shehane
I could figure out what was the problem with CLA so I solved it, PR should be fine now.
Thanks for your support Jennifer 👍

I manually tested the given examples in the original issue. They no longer error. Additionally, they are all available properties on the Cypress.config() as expected.

The configuration in the Settings also displays the objects and arrays correctly appended to the config.

Looks great. Thanks for the contribution! 💯

@jennifer-shehane should this PR also resolve #7002 and #1736

[jennifer-shehane]

@mccataldo Yes! It does appear to have also fixed those issues. Nice catch 👍 I'll update those other issues to reflect that they've been fixed.
