Hey there! :)

There are two problems with your current setup.

1. As stated in the Cypress Documentation, you need instrument your code yourself for the code coverage to take effect: https://docs.cypress.io/guides/tooling/code-coverage#Instrumenting-code

2. You use vite to build your cypress and storybook setup. Using istanbul to instrument your code with vite requires using vite-istanbul-plugin but there's an open issue on that plugin with compatibility with nx repos: window__coverage__ is undefined on nx workspace iFaxity/vite-plugin-istanbul#94

Unfortunately, these are tools that we do not control and the issues lie outside the scope of Nx. Therefore, I'm going to close this issue.

You should raise an issue on the cypress repo and follow along with the issue listed above for vite-istanbul-plugin.
