I have passed the api response value from one function to another function, But in JEST unit test case showing undefined, How to solve this error

angular code

  this.content = this.commonSiteContent();
 this.passingvalue(this.content.name);


 jest.spyOn(srvice, 'commonSiteContent').mockReturnValue(mockContent);
component.ngOnInit();
expect(mockContent.getContentDetails).toHaveBeenCalledWith("sss");
expect(component.passvalue).toHaveBeenCalled()

I got the below error

TypeError: Cannot read property 'name' of undefined

  27 |   
  28 |
  29 |     this.passvalue(this.content.name);
     |                                     ^
  30 |   }
  31 |   passvalue(name="" ){

The content doesnt have property `name` either you can assign the content object or use safe navigator operator `?` i.e `this.passvalue(this.content?.name);` – Kamran Khatti Aug 02 '21 at 10:06
The content values return from API, After getting just pass another function @KamranKhatti – shanmugakumar Aug 02 '21 at 10:35
Not sure how you implemented and can not provide solution without seeing the code if you have any working example may be on stackblitz etc then it will help to fix. – Kamran Khatti Aug 02 '21 at 10:37
I have updated angular and unit test code – shanmugakumar Aug 02 '21 at 10:51
