[fs] Value is sometimes an empty string

[kaaax0815]

Environment

node v22.11.0
macos 14.7.1

Reproduction

Describe the bug

Can't reproduce on stackblitz but on local maschine.
As you can see in the code

if (b.some((v) => v.status === 'fulfilled' && v.value === '')) {
  console.log('Something went wrong');
}

it checks if v.value is an empty string (which should never be the case)

but I still get this log
