Thats probably the problem, you get this error if you go to the checkout page.

[Kuncy]

The main problem is in the shipping-details.component.ts

authService.user$.pipe(

  map((user) => {
    
    this.userDetails = user;
    console.log(user);
  })
);

We get nothing here if you console log the user or the userDetail like i did, you get undefined back.
So probably there is a problem with the ngmodels in the html i think.
