Failed to convert from type [byte[]] to type [java.lang.Object] for value - spring

Question

I want to add a method to check if the user has the USER role. In the same way it is checked whether the user is ADMIN. When adding a method, this error appears. This is my User.class. Don't know how to fix this because don't have much excperince in Spring boot
User.class
#Entity
#Table(name = "usr")
public class User implements UserDetails {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
#NotBlank(message = "Заполните имя пользователя")
private String username;
#NotBlank(message = "Заполните пароль")
private String password;
private boolean active;
private String name;
private String phone;
private String email;
private String activationCode;
#ElementCollection(targetClass = Role.class, fetch = FetchType.EAGER)
#CollectionTable(name = "user_role", joinColumns = #JoinColumn(name = "user_id"))
#Enumerated(EnumType.STRING)
private Set<Role> roles;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getUsername() {
return username;
}
#Override
public Collection<? extends GrantedAuthority> getAuthorities() {
return getRoles();
}
public boolean isAdmin() {
return roles.contains(Role.ADMIN);
}
public boolean isDriver() {
return roles.contains(Role.DRIVER);
}
public boolean isUser() {
return roles.contains(Role.USER);
}
