[WORDPRESS PLUGIN] Error fired on TinyMce Button

[hellosubotai]

Hello,
I just tried to test your plugin for WordPress which I got here : https://github.com/highcharts/highcharts-editor/releases

It installs correctly and the new button displays well in the content editor.

Problem encountered: When I click on the button to display the chart editor, a red message appears and says:

There's a problem with your chart!
[object Object]

And I can't play with the data or display it as a graph.

Clarification: I am in freshly updated WordPress 5.5.

Thank you

I have exact the same problem on WordPress 5.4.2.

Error is code: TypeError: Cannot read property 'prototype' of undefined at setupAnnotationEvents

Anybody knows how to solve this problem ?

[mvirenius]

It seems that Highchart.Annotation module is not defined in highcharts-editor.min.js.

Same issue in Wordpress 6.0 running the pre-built stable version of the plugin.
