Watchman errors when doing a detox build

[Fishbowler]

• Your Rocket.Chat Experimental app version: 4.7.1
• Your Rocket.Chat server version: n/a
• Device (or Simulator) you're running with: iOS 13.5

When preparing to run test, I first build by running:
detox build -c ios.sim.release

Early on in the process, this sometimes occurs:

jest-haste-map: Watchman crawl failed. Retrying once with node crawler.
Usually this happens when watchman isn't running. Create an empty .watchmanconfig file in your project's root folder or initialize a git or hg repository in your project.
Error: Watchman error: too many pending cache jobs. Make sure watchman is running for this project. See https://facebook.github.io/watchman/docs/troubleshooting.html.

Build still succeeds, but it's slow. Maybe it's always slow, or maybe this is causing some suboptimal behaviour 🤷

Kind of not related to this repo.
It's an error on detox or watchman.
