How to map fetched JSON to the existing object in TypeScript

I have a problem with mapping fetched JSON from the API to an existing object. TypeScript code:

enter image description here

Hero Interface:

export interface Hero {
   id: number;
   name: string;
}

Console log:

enter image description here

this.hero is always empty (undefined). How to solve this PS. I'm new in Angular and typescript.

Solution

    this.hero = fetchedHero[0];
