Jest related error when running gridsome develop

[marcfilleul]

Here is a link to a bug issue opened i gridsome github but apparently related to Jest:

gridsome/gridsome#252 (comment)

This example doesn't work in the latest version (jest-worker@24.3.0) because stderr is null when setting silent: false or stdio as anything other than 'pipe'.

const worker = new Worker('/path/to/worker.js', {
  forkOptions: {
    silent: false
  }
})

The error message:

stderr is null - this should never happen. Please open up an issue at https://github.com/facebook/jest

I've reproduced this same issue.

Thanks @hjvedvik! That makes perfect sense. We made the change since we got a type error - turns out our internal types were wrong (not really surprising)! Will have a PR with a fix up shortly
