Setting up Cypress using webpack 5 and react-scripts
See original GitHub issueCurrent behavior
I am facing an issue with setting up Cypress with webpack 5. When I run the test end-to-end It works properly, but when I run the component test (cypress run-ct) I got an error. Follow the errro below:
What I could notice is I’m using the react-scripts library and it is using webpack 4 under the hood. I tried to use webpack-5-react-scripts but it didn’t work as well.
Anyone has already faced this before?
