Fails test when assert { type: 'json' } is used

[aMediocreDad]

Describe the bug

I have noticed I cannot use the import type assertions that were included with Node 16.14.2 and onwards.

With Node 16.14.2, JSON import in ESM modules have landed on the same spec as browsers.

import jsonFile from './some-json.json' assert { type: 'json' }

However using this syntax in a test module or any module imported (recursively) by Vitest results in a syntax error.

This is somewhat strange as Vite otherwise bundles files like these without issue.

Reproduction

See an example based on the basic example in this repo: https://github.com/aMediocreDad/vitest-json-assert

Stackblitz cannot be used due to lack of support for LTS node.

Sorry, this is indeed a Vite issue. I am curious as to why it seems to work fine in my project (there is Typescript, Svelte, and Esbuild otherwise involved so could be one of those).

It works for you because it is not processed by ssr. Ssr rewrites imports to a custom function, that's why assertions are left out
