Annotations not working

[revisionfour]

I am having an issue with annotations in my project.

I have created this example which shows annotations working in a sandbox environment. It appears it will only work with highcharts version 6.0.6.
https://codesandbox.io/s/1rq3vl1vr4

However I am having an issue in my project using the same versions

In my project I have the lines
import Annotations from 'highcharts/modules/annotations';
import ReactHighcharts from "react-highcharts";

Annotations(ReactHighcharts.Highcharts);

I'm getting this error
Annotations(ReactHighcharts.Highcharts);

In my package.json I'm using
"highcharts": "6.0.6",
"react-highcharts": "16.0.2",

Any ideas?
