Getting error command failed.

Hey @IjzerenHein I am using RN-0.63. I am getting a few exceptions when running the command. Command : ./node_modules/.bin/react-native-bundle-visualizer --verbose --platform android --dev true --entry-file ./index.js Output: Generating bundle...

In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

Can you please let me know the solution for this.

Hmm interesting. Which node version are you using?

[SMhdAsadi]

I have the same problem with node v18.2.0 & ReactNative v0.66.1.

Same problem, exact output:

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

UPDATE ##FIX

Hey everyone, I was just trying possible solutions, and when I downgrade my node version to 16.4.0 it worked like charm. For anyone in to this issue 🥳

I made a potential fix https://github.com/IjzerenHein/react-native-bundle-visualizer/issues/112

The error you guys are facing, it happens on node version 18. A couple of days ago we fixed this https://github.com/IjzerenHein/react-native-bundle-visualizer/pull/101. We will be releasing a newer version of this package shortly which will fix this. 🙂
