На Spring пишу мэсседжер, при попытке создать ассоциацию друзей через @OneToMany в зависимости от fetchType выдает разные ошибки

Весь код сущности

@Entity
public class User implements UserDetails {

public User() {

}

public User(String nick, String pass, String name, String surname, String email, boolean isActivated) {
    this.username = nick;
    this.password = pass;
    this.name = name;
    this.surname = surname;
    this.email = email;
    this.isActivated = isActivated;
}

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;

private String username, password, name, surname, email;

boolean isActivated;

@OneToMany(targetEntity = Dialogue.class, cascade = CascadeType.ALL, fetch = FetchType.EAGER)
private Collection<Dialogue> dialogues = new ArrayList<>();

public Collection<Dialogue> getDialogues() {
    return dialogues;
}

public void setDialogues(Collection<Dialogue> dialogues) {
    this.dialogues = dialogues;
}



public Collection<User> getFriends() {
    return friends;
}


public void setFriends(Collection<User> friends) {
    this.friends = friends;
}

@OneToMany(targetEntity = User.class, cascade = CascadeType.ALL, fetch = FetchType.EAGER)
private Collection<User> friends = new ArrayList<>();


@ElementCollection(targetClass = Role.class, fetch = FetchType.EAGER)
@CollectionTable(name = "user_role", joinColumns = @JoinColumn(name = "user_id"))
@Enumerated(EnumType.STRING)
private Set<Role> roles;

public Long getId() {
    return id;
}

public void setId(Long id) {
    this.id = id;
}

public void setUsername(String username) {
    this.username = username;
}

public void setPassword(String password) {
    this.password = password;
}

@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
    return null;
}

@Override
public String getPassword() {
    return password;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getSurname() {
    return surname;
}

public void setSurname(String surname) {
    this.surname = surname;
}

public String getEmail() {
    return email;
}

public void setEmail(String email) {
    this.email = email;
}

public boolean isActivated() {
    return isActivated;
}

public void setActivated(boolean activated) {
    isActivated = activated;
}

public Set<Role> getRoles() {
    return roles;
}

public void setRoles(Set<Role> roles) {
    this.roles = roles;
}

@Override
public String getUsername() {
    return username;
}

@Override
public boolean isAccountNonExpired() {
    return true;
}

@Override
public boolean isAccountNonLocked() {
    return true;
}

@Override
public boolean isCredentialsNonExpired() {
    return true;
}

@Override
public boolean isEnabled() {
    return isActivated();
}

"Больная часть"

@OneToMany(targetEntity = User.class, cascade = CascadeType.ALL, fetch = FetchType.EAGER)
    private Collection<User> friends = new ArrayList<>();

public Collection<User> getFriends() {
    return friends;
}


public void setFriends(Collection<User> friends) {
    this.friends = friends;
}

При fetchType Eager выдаёт ошибку

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dialogueRepository' defined in Kejkers.Rgr.repo.DialogueRepository defined in @EnableJpaRepositories declared on JpaRepositoriesRegistrar.EnableJpaRepositoriesConfiguration: Cannot resolve reference to bean 'jpaMappingContext' while setting bean property 'mappingContext'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaMappingContext': Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory; nested exception is org.hibernate.loader.MultipleBagFetchException: cannot simultaneously fetch multiple bags: [Kejkers.Rgr.Models.User.dialogues, Kejkers.Rgr.Models.User.friends]

при fetchType LAZY сервер запускается, однако при посещении страницы

@GetMapping("/friends")
public String friends (@AuthenticationPrincipal User user, Model model)
{
    Iterable<User> friends = user.getFriends();
    model.addAttribute("friends",friends);
return "friends";
}

Всё ломается

org.thymeleaf.exceptions.TemplateInputException: An error happened during template parsing (template: "class path resource [templates/friends.html]")

при поиске проблемы с помощью точки останов выдает такую строчку

Unable to evaluate the expression Method threw 'org.hibernate.LazyInitializationException' exception.

@Transactional пробовал, костыли пробовал.
