Translation Error with '@shopify/react-i18n' Package in Production Build

[kmajay978]

I am using this package import { I18nContext, I18nManager } from '@shopify/react-i18n'; to translate my app.

It's working fine in case of dev environment, but once i make the build, it starts giving me error. and i am not able to figure out why it's causing an issue. Kindly help me out.

ERROR I am getting in react build

This is how i am using app js sample code
App.js

import {
  NavigationMenu,
  Provider as AppBridgeProvider,
} from "@shopify/app-bridge-react";
import { AppProvider as PolarisProvider, Frame } from "@shopify/polaris";

import { I18nContext, I18nManager } from '@shopify/react-i18n';

const [locale, setlocale] = useState('en');
const i18nManager = new I18nManager({
    locale,
    onError(error) {}
  });

    <I18nContext.Provider value={i18nManager}>

In pages (Analytics ) this how i am using

import { useI18n } from '@shopify/react-i18n';
import en from "../translation/en.json";

const Analytics = () => {

  const [i18n] = useI18n({
    id: 'Translations',
    fallback: en,
    translations(locale) {
      // return locale === "en" ? en : es;
      return import(`../translation/${locale}.json`);
    }
  });

 return (
    <Page 
    backAction={{content: i18n.translate('Translations.analytics.heading'), onAction: () => navigate('/')}}
    title={i18n.translate('Translations.analytics.heading')}
    />
