Unable to download JS bundle

[Juanxpeke]

Hi, I followed Vision Camera official documentation and installed react-native-worklets-core to be able to use frame processors for react-native-vision-camera, however, I keep getting the following error when I try to run the app.

I just tried this on a new react native project, and I noticed it appears when I use the worklet feature on a function. The code of App.tsx is the following:

import { useEffect, useState } from 'react';
import { StyleSheet, Text, View } from 'react-native';
import { Camera, Frame, useCameraDevice, useCameraPermission, VisionCameraProxy } from 'react-native-vision-camera';

const plugin = VisionCameraProxy.initFrameProcessorPlugin('detectFaceLandmarks', {})

export function detectFaceLandmarks(frame: Frame) {
  'worklet' // The error disappears when this line is commented
  if (plugin == null) {
    throw new Error("Failed to load Frame Processor Plugin!")
  }
  return plugin.call(frame)
}


function App() {
  const [cameraActive, setCameraActive] = useState(false);

  const device = useCameraDevice('front');
  const { hasPermission, requestPermission } = useCameraPermission();

  useEffect(() => {
    const init = async () => {
      const requestedPermission = await requestPermission();
      setCameraActive(hasPermission || requestedPermission);
    };
    init();
  }, []);

  if (device == null) return <View><Text>No tiene camara</Text></View>
  if (!cameraActive) return <View><Text>No tiene permisos</Text></View>
  return (
    <Camera
      style={StyleSheet.absoluteFill}
      device={device}
      isActive={cameraActive}
    />
  )
}

export default App;

And my dependencies are:

  "dependencies": {
    "@react-native/new-app-screen": "0.84.1",
    "react": "19.2.3",
    "react-native": "0.84.1",

Did I configure something wrong? Any help is appreciated.

I created a new project using only React Native 0.82 and react-native-worklets-core, and I get the same error on the Android Studio terminal:

It worked by manually installing @babel/plugin-proposal-nullish-coalescing-operator, @babel/plugin-proposal-optional-chaining and @babel/preset-typescript. Is this ok? The terminal says those packages are way long deprecated.
