I want to get value in list object in Angular.

Here is my component

 getAllStories():void{
    this.service.getAllStories().subscribe(
      ls => {
        this.StoriesList = ls;
        for ( let i  of this.StoriesList){
          console.log(i);
          console.log(i?.$Name)
         }
      }
    )
  }

This's my console log. when i show object it show exactly. but I get property of this object it show undefined.

Thanks for your help!!
