Same here. My cypress and cypress-vite versions are equal. My general vite version is 5.0.10. I thought maybe downgrading to 4.5 fixes the issue, as Cypress shows compatibility warnings with version 5, but unfortunately it didn't :(

@matthiasmoke

Made it work by changing my cypress.config.ts to JS (cypress.config.js)

const { defineConfig } = require('cypress')
const vitePreprocessor = require("cypress-vite");

module.exports = defineConfig({
    e2e: {
        setupNodeEvents(on) {
            on('file:preprocessor', vitePreprocessor())
        }
    },
});

🤷

Duplicate of #13. @ethonai-dino I think this should help and you don't need to change your config to js.
