Getting TS error extending EventModel class

[marciogurka]

Forum post

In the following versions

"@bryntum/scheduler": "^5.0.6",
"@bryntum/scheduler-angular": "^5.0.6",

eg I have

import { EventModel } from '@bryntum/scheduler/scheduler.lite.umd.js';

export class SchedulerEventModel extends EventModel {

static get fields() {
    return [
      'localEdits',
      ... etc

And then I supply this when I instantiate the EventStore

 this.eventStore = new EventStore({
        modelClass: SchedulerEventModel,
        data: []
      });

However, that is causing a TS error, even with all set as the Bryntum documentation.
