With Cypress, you can easily create tests for your modern web applications, debug them visually, and automatically run them in your continuous integration builds.

You are running your tests from the wrong location, `/e2e` is not correct. So you got that error because of running Cypress from inside `/e2e` folder.
You run Cypress command from the root, i.e. same level as the Cypress folder (not inside of it). Also remove that `cypress.config.js` from inside `e2e` and put it also on the root.
