Upgrading to Cypress@7.4 - plugins file unable to find module @cypress/webpack-preprocessor

[christofer-castillo]

Hey all. So I have been using Cypress@6.7.1 and everything works fine. I wanted to upgrade to take advantage of the new cy.intercept features. No config has changed between the two versions, however, I get the error message Error: Cannot find module '@cypress/webpack-preprocessor'.

This is the stack trace. Any idea on what exactly is causing this.

Maybe you should log a bug, not a discussion for this kind of matter :|
