Get cart by user id didn't work

[LeQuoc-Dat]

Here my code

private userCartURL = 'https://dummyjson.com/carts/user/'

 getUserCart(userID: number): Observable<any>
    {
        return this.http.get<Cart>(`${this.userCartURL}${userID}`).pipe(
            tap(res =>
            {
                console.log(`${this.userCartURL}${userID}`)
            }
            )
        )
    }

The result :
