Unable to use amCharts in tests: export { System, system } from "./.internal/core/System";

Question

I am using a fairly basic site setup with react-create-app and then importing as the documentation suggests: import * as am4core from '@amcharts/amcharts4/core'

There is no problem at all whilst using the charts, however when I run them in the test environment they fail with the below error.

   Details:

    /var/www/management/node/node_modules/@amcharts/amcharts4/core.js:8
    export { System, system } from "./.internal/core/System";
    ^^^^^^

    SyntaxError: Unexpected token 'export'

Versions

• amcharts4: v4.8.1
• react-scripts: v3.3.0

ProvenanceChart/index.js

/* eslint-disable no-unused-vars */
import React from 'react'
import * as am4core from '@amcharts/amcharts4/core'
import * as am4maps from '@amcharts/amcharts4/maps'
import am4geodata_worldLow from '@amcharts/amcharts4-geodata/worldLow'

import am4themes_animated from '@amcharts/amcharts4/themes/animated'

import { theme } from 'config/theme'

am4core.useTheme(am4themes_animated)

class ProvenanceChart extends React.Component {

I do not believe I am doing anything outwardly different from a standard stack.

Test in question:

  it('should render', () => {
    expect(renderer.create(getComponent()).toJSON()).toMatchSnapshot()
  })

Project jest.config.js

module.exports = {
  "roots": [
    "<rootDir>/node/src"
  ],
  "moduleFileExtensions": [
    "js",
    "jsx",
    "json",
    "node"
  ],
  "verbose": true,
  "testEnvironment": 'node',
  "testURL": 'http://localhost:3000',
  "setupFiles": ["jest-canvas-mock"],
  "setupTestFrameworkScriptFile": "<rootDir>/src/setupTests.js"
      //// setup file
       //import { configure } from 'enzyme';
       //import 'jest-canvas-mock';
       //import Adapter from 'enzyme-adapter-react-16';

       //configure({ adapter: new Adapter() });
}

Then finally ran with npm test
