i got that error too, and still get error when add modal.overlay.defaultViewContainer = vcRef; ==> Property 'defaultViewContainer' does not exist on type 'Overlay'.

hey i just fixed by included to main template and remove modal.overlay.defaultViewContainer = vcRef; or overlay.defaultViewContainer = vcRef;

here is my app.component.ts: ```javascript @Component({ selector: 'app', styleUrls: ['./app.component.scss'], template: ` ` }) ```
