EMFILE: too many open files, watch

i'm facing below issue while generating archive in xcode

```
node:events:371
throw er; // Unhandled 'error' event
^

Error: EMFILE: too many open files, watch
at FSEvent.FSWatcher._handle.onchange (node:internal/fs/watchers:204:21)
Emitted 'error' event on NodeWatcher instance at:
at NodeWatcher.checkedEmitError (/Users/igesia/work/mobile/igesia_mobile/node_modules/sane/src/node_watcher.js:143:12)
at FSWatcher.emit (node:events:394:28)
at FSEvent.FSWatcher._handle.onchange (node:internal/fs/watchers:210:12) {
errno: -24,
syscall: 'watch',
code: 'EMFILE',
filename: null
}
```

i'm on ```2021.06.07.00``` version of watchman

any idea how to fix this?
