Spring Data JPA unable to find object with id

I'm using JPA + Hibernate + Spring Data JPA on my project for working with database (MySQL).
Recently I've got an error which says:

org.springframework.orm.jpa.JpaObjectRetrievalFailureException: Unable to find com.kanda.mindwire.domain.results.CognitiveResult with id 1700; nested exception is javax.persistence.EntityNotFoundException: Unable to find com.kanda.mindwire.domain.results.CognitiveResult with id 1700

The code is trying to fetch the list of Employee entity which is having a OneToOne relation with CognitiveResult. I was thinking that it might be that there are Employee row with cognitive_id=1700 but when I query my db I see that there are no such row.

The question is from where hibernate takes this id and how to fix it?

Here is my code:
Employee.java

@Table(uniqueConstraints = @UniqueConstraint(columnNames = {Employee_.EMAIL}))
@Entity
@Data
public class Employee extends BaseEmployee {

@Column
private String email;
....
@ManyToOne
@JoinColumn(name = "company_id")
private Company company;
    
@OneToOne(cascade = CascadeType.ALL, orphanRemoval = true)
@JoinColumn(name = "cognitive_id", referencedColumnName = "id")
private CognitiveResult cognitiveResult;
...
}

CognitiveResult.java

@Entity
@Table(name = "cognitive_results")
@Data
public class CognitiveResult extends BaseAssesment {
...

@OneToOne(mappedBy = "cognitiveResult")
private Employee employee;

@PreRemove
public void removeCognitiveForEmployee() {
    if (employee != null) {
        employee.setCognitiveResult(null);
    }
}
...
}

EmployeeRepository.java

public interface EmployeeRepository extends BaseRepository<Employee> {
...
    List<Employee> findByCompany(Company company);
...
}

Company.java

@Entity
@Data
public class Company extends BaseSettingsEntity {
...
@OneToMany(mappedBy = "company", cascade = CascadeType.ALL)
private Set<Employee> employees = new HashSet<>();
/**
 * Logic for syncing employees
 * @param employee
 */
 public void removeEmployee(Employee employee) {
    if (!employees.contains(employee)) {
        return;
    }

    employees.remove(employee);
    employee.setCompany(null);
 }

 public void addEmployee(Employee employee) {
    if (employees.contains(employee)) {
         return;
    }

    employees.add(employee);
    employee.setCompany(this);
 }
...
}

All of my domain models inherit from BaseEntity.java

@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
@Entity
@Data
public abstract class BaseEntity {
@Id
@GeneratedValue(strategy = GenerationType.TABLE)
@Column(updatable = false, nullable = false)
protected Long id;
...
}

And the exception occurs while calling findByCompany:

@Slf4j
public class EmployeeService extends BaseEntityService<Employee> {

private final EmployeeRepository repo;

public Map<String, Map<EmployeeJob, List<Employee>>> findWithFilter(EmployeeFilterWrapper filter, String username) {
    List<Employee> employeeList;
    User user = userService.findByUsername(username);
    Company company = user.getCompany();
    if (company == null)
        throw new InvalidCompanyException("Company not assigned for a user!");

    if (filter != null && filter.getDivisionsFilter() != null && CollectionUtils.isNotEmpty(filter.getDivisionsFilter().getDivisions())) {
        employeeList = repo.findEmployeeByDivisionNamesAndCompany(filter.getDivisionsFilter().getDivisions(), company.getName());
    } else {
        employeeList = repo.findByCompany(company);
    }
...
}

Found an issue. There where a link to missing cognitive_id in another table and it is missing because I was clearing those entites directly in db recently, but forgot that they reference other table.
It was a Supervisors table which is inherited from Employee

@Entity
@Table(name = "supervisors")
@Data
public class Supervisor extends Employee {
...
}
