Possible Cypress related issue with package.json scripts setup

[cfjedimaster]

I scaffolded a new application with npm init vue@latest, and during the prompts, I selected YES to Cypress. After it was done, I went into the directory, ran npm i, and then tried:

npm run test:e2e

When I did, it hung at:

I asked around on the Cypress discord, and did some digging, and noticed the following.

If I did npm run dev, of course the Vue app worked fine. But if I ran the preview task as created during scaffolding, vite preview --port 4173, it did NOT build the Vue app. I'd hit the URL and get, "Cannot GET /" (or something like that ;).

If I remove 'preview' from the command:

    "preview": "vite --port 4173",

I can then run the test:e2e task ok.

So there's definitely a workaround, but "out of the box", it seems like the scaffolded scripts may be wrong?

The generated README has explicitly stated that build should be run before test:e2e
