ChunkLoad Error

[varunraghu3112]

Getting ChunkLoadError if there is a lazy load import

For example:
const Modal = React.lazy(() => import('../_game/ModalA'));

when this Modal is used Im getting a chunkLoadError, how to resolve this ?

Im just setting up repack for my project so I might be missing something

My config file:

import { createRequire } from 'node:module';
import path from 'node:path';
import TerserPlugin from 'terser-webpack-plugin';
import * as Repack from '@callstack/repack';

const dirname = Repack.getDirname(import.meta.url);
const { resolve } = createRequire(import.meta.url);

export default (env) => {
  const {
    mode = 'development',
    context = dirname,
    entry = './index.js',
    platform = process.env.PLATFORM,
    minimize = mode === 'production',
    devServer = undefined,
    bundleFilename = undefined,
    sourceMapFilename = undefined,
    assetsPath = undefined,
    reactNativePath = resolve('react-native')
  } = env;

  if (!platform) {
    throw new Error('Missing platform');
  }

  process.env.BABEL_ENV = mode;

  const alias = {

  };

  return {
    mode,
    devtool: false,
    context,
    entry: [
      ...Repack.getInitializationEntries(reactNativePath, {
        hmr: devServer && devServer.hmr
      }),
      entry
    ],
    resolve: {
      ...Repack.getResolveOptions(platform),
      alias
    },
    output: {
      clean: true,
      hashFunction: 'xxhash64',
      path: path.join(dirname, 'build/generated', platform),

Im not getting this error if I don't have a Lazy import

@jbroma can you help me out for this issue ?

[jbroma]

@varunraghu3112 it looks to me that you might need to configure resolver through ScriptManager.shared.addResolver. Please check out the documentation that we have here: https://re-pack.dev/docs/code-splitting/usage
