This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch().

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch react-native-bundle-visualizer@3.1.1 for the project I'm working on.

This is a fix proposal to this issue https://github.com/IjzerenHein/react-native-bundle-visualizer/issues/38

node:internal/process/promises:288
            triggerUncaughtException(err, true /* fromPromise */);
            ^

[UnhandledPromiseRejection: This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason "#<Object>".] {
  code: 'ERR_UNHANDLED_REJECTION'
}

Node.js v18.0.0

Here is the diff that solved my problem:
