with node 16 "assert {type: 'json'}" is required but can't be parsed by vitest

[francois-spectre]

Describe the bug

With node >= 16.14, importing a json file require to add an assertion like

import pkg from '../package.json'  assert {type: 'json'}

If I don't provide it, I get an error ERR_IMPORT_ASSERTION_TYPE_MISSING
If I provide it, it breaks the vitest run with

Error: Parse failure: Unexpected token (18:33)
Contents of line 18: import pkg from '/package.json'  assert {type: 'json'}

Reproduction

• try to import a json file with node > 16.14
• add the json assertion assert {type: 'json'}
• run the tests

Vitest doesn't parse anything, please follow Vite issue: vitejs/vite#4934

[francois-spectre]

ok yes thank you for the link to the vite issue.
But it seems that it is merged in vite but still not working with vitest (I have just tried with the last version 0.17.1)

I don't think Vite released a new version with a fix, it was merged 2 days ago. You would also need Vite 3 for this to work

[francois-spectre]

oh yes so I tried with 3.0.0-beta.7 and it is working! thank you!
