Can not set property of Undefined.Why??

i dont know what wrong with this code. It giving the error cannot set the phone propert of undefined(Owner is object for which we need to set phone property). but when we check Owner object it is available

class Pet{
  constructor(animal,age,breed,sound){
  this.animal=animal;
  this.age=age;
  this.breed=breed;
  this.sound=sound;
  }

 get activity(){
const today=new Date();
const hour=today.getHours();
  if(hour>8 && hour<20){
    return 'Playing'
    }
  else{
    return 'Sleeping'}
}
 get onwer(){
   return this._owner;
 }
set owner(ownerName){
 this._owner=ownerName;
  console.log(`Setter Called: ${this._owner}`)
}

}
class Owner{
  constructor(name,address){
    this.name=name;
    this.address=address;
  }
  set phone(phone){
  const phoneNormalized=phone.replace(/[^0-9]/g,'');
  this._phone=phoneNormalized;
  }
  get phone(){
      return this._phone
  }
}

  const ernie=new Pet('dog',8,'sheffered');
 ernie.owner=new Owner("Muhammad Ali","Ranjha");
 ernie.owner.phone='(555) 456-9788';
console.log(ernie.onwer);

Hi there, Muhammad Ali! You just have a couple of typos here and there. For instance, around line 18, you typed get onwer(), but you meant to type get owner(). Note that the "n" and "w" are backward in your version. In the console.log() on the very last line you have the same type of misspelling. You typed ernie.onwer but you meant to type ernie.owner.

Hope this helps! :sparkles:
