Parameter value [6] did not match expected type [java.lang.Long (n/a)] in Spring Boot - spring-boot

Question

I am a beginner in Spring Boot and I have two table which having One to One relationship. The problem is when I am trying to get user record by its user-id I am getting an exception like below.
I pasted all my code. What is the mistake in my code?
Users
#Entity
#Table(name = "users")
public class User implements Serializable {
#Id
//#GeneratedValue(strategy = GenerationType.IDENTITY)
#GeneratedValue(strategy= GenerationType.AUTO)

#NotNull
#Size(max = 65)
#Column(name = "first_name")
private String firstName;
#Size(max = 65)
#Column(name = "last_name")
private String lastName;
#NotNull
#Email
#Size(max = 100)
#Column(unique = true)
private String email;
#NotNull
#Size(max = 128)
private String password;
#OneToOne(fetch = FetchType.LAZY,
cascade = CascadeType.ALL,

private UserProfile userProfile;
// Hibernate requires a no-arg constructor
public User() {
}
public User(String firstName, String lastName, String email, String password) {
this.firstName = firstName;
this.lastName = lastName;
this.email = email;
this.password = password;
}
// Getters and Setters (Omitted for brevity)
