In-app purchase issue

https://devdactic.com/ionic-in-app-purchase-capacitor/
I followed your tutorial and got an unknown issue in my project.
I added two non-consumable products on App store, and Apple has approved these two products, And I tried to get the products in my ionic/capacitor project.
this.store.ready(() => {
this.products = this.store.products;
console.log(product list: ${JSON.stringfy(this.products)});
this.ref.detectChanges();
})
This is the code to get the product list I tried.
Upon checking the response, the title, description, price is null


I am not sure why I got null from the response.
Could you help me?
