NullPointerException thrown when quering 4 th ManyToOne object

[recepp]

I have 4 objects which associated with ManyToOne like shared below.

Exception thrown for this query.
query -> eventDeifiniton.eventA.eventB.eventC.name==test.
Exception -> java.lang.NullPointerException: Cannot invoke "com.querydsl.core.types.Path.getType()" because "path" is null

Exception fixed by adding QueryInit to EventDefinition.java.

@QueryInit("eventB.eventC")
private EventA eventA;

Do we have anothor way to fix this exception without @QueryInit?

--------------Objects----------------

`public class EventDefinition extends BaseEntity {

private String name;

@ManyToOne(fetch = FetchType.LAZY)
@JsonManagedReference
@JoinColumn(name = "event_a_id")
//@QueryInit("eventB.eventC")
private EventA eventA;

}`

`public class EventA extends BaseEntity {

@ManyToOne(fetch = FetchType.LAZY)
@JsonManagedReference
@JoinColumn(name = "event_b_id")
private EventB eventB;

private String name;

}`

`public class EventB extends BaseEntity {

@ManyToOne(fetch = FetchType.LAZY)
@JsonManagedReference
@JoinColumn(name = "event_c_id")
private EventC eventC;

private String name;

}`

public class EventC extends BaseEntity<UUID> { private String name; }
