Error in Angular Reactive Forms: Unable to access the 'group' property due to its undefined value

This query is different from 

https://stackoverflow.com/questions/52235952/cannot-read-property-of-undefined-reactive-forms

Check out the StackBlitz demo here - https://stackblitz.com/edit/github-rbjwcd-wtrevw

I am encountering some challenges with the aforementioned demo. My goal is to make the form builder work with models as shown in the example. The trouble lies with the .group property.

contactForm: FormGroup;

  createFormGroupWithBuilderAndModel(formBuilder: FormBuilder) {
    return this.formBuilder.group({
      personalData: formBuilder.group(new PersonalData()),
      requestType: '',
      text: ''
    });
  }

I suspect that the issue might be related to not initializing the form upon return like so:

this.contactForm = this.formBuilder.group

Can anyone assist in resolving this matter?
