I am trying to generate Organization charts using highcharts and highcharts-angular. However, it is throwing below error while loading organization chart module.
organization.js:9 Uncaught TypeError: Cannot read property 'prototype' of undefined

at e (organization.js:9)

Is there some wrong I am doing? I am using same code for generating network charts and it is working without any issue. I am facing this issue only with Organization chart.
Loading Organization chart:
import { Component, OnInit } from '@angular/core';
import * as Highcharts from 'highcharts';
import HighchartsOrganization from "highcharts/modules/organization";
import HighchartsExporting from "highcharts/modules/exporting";
HighchartsOrganization(Highcharts);
HighchartsExporting(Highcharts);
Loading Network chart: No issue in this case
import { Component, OnInit } from '@angular/core';
import * as Highcharts from 'highcharts';
import HighchartsNetworkgraph from "highcharts/modules/networkgraph";
import HighchartsExporting from "highcharts/modules/exporting";
HighchartsNetworkgraph(Highcharts);
HighchartsExporting(Highcharts);
The Organization chart module requires the Sankey diagram module so you need to import that first, e.g.:
import { Component, OnInit } from '@angular/core';
import * as Highcharts from 'highcharts';
import HighchartsSankey from "highcharts/modules/sankey";
import HighchartsOrganization from "highcharts/modules/organization";
import HighchartsExporting from "highcharts/modules/exporting";
HighchartsSankey(Highcharts);
HighchartsOrganization(Highcharts);
HighchartsExporting(Highcharts);
See official Highcharts Organization example which imports sankey.js
