ERR_IPC_CHANNEL_CLOSED: Channel closed

When I try to call an async function from dialog.showOpenDialog I get this error and the window crashes:

called function:

import { createWorker } from 'tesseract.js'
const path = require('path')

const worker = createWorker();

export default async function imgToText(imgFilePath: string): Promise<void> {
  const image = path.resolve(__dirname, imgFilePath)
  await worker.load();
  //await worker.loadLanguage('eng');
  //await worker.initialize('eng');
  //const { data: { text } } = await worker.recognize(image);
  //console.log(text);
  //await worker.terminate();
}

This is the calling function :

async function loadFile() {
  dialog.showOpenDialog({
    properties: ['openFile', 'multiSelections'],
  }).then(result => {
    result.filePaths.forEach((filepath: string) => {
      imgToText(filepath);
    })
  }).catch(err => {
    console.log(err)
  })
}

I am also getting the same error.

Closing this issue as the master branch now uses worker_threads rather than child_process (per #630). Therefore, you should not encounter this particular error again. If you encounter a new error, feel free to open a new issue.
