IntelliJ run spring boot JPA application says not-null property references a null or transient value , But working fine from terminal - spring

Question

I have a microservice project using Spring Boot: 2.6.2, JPA, and H2 DB with JAVA 17.
when I run my project from IntelliJ as an application from configuration it shows the below exception while inserting data into DB:
Caused by: org.hibernate.PropertyValueException: not-null property references a null or transient value
But when I run this project from the command line or STS it's working fine, There is no exception. And entry was inserted properly.
I am using H2 Db as a datasource at my application.yml for local run.
spring:
datasource:
url: jdbc:h2:mem:test;DB_CLOSE_ON_EXIT=TRUE;DB_CLOSE_DELAY=5
driverClassName: org.h2.Driver
username: admin
password: admin
In this application.yml flyway is also used but that is only for the dev env profile.
The entity that is showing issue for :
#Getter
#Setter
#ToString(callSuper = true)
#SuperBuilder(toBuilder = true)
#EqualsAndHashCode(callSuper = false)
#NoArgsConstructor
#AllArgsConstructor
#Entity
#Table(name = "EMPLOYEE")
public class Employee extends Basics {
#Id
#SequenceGenerator(
name = "ID",
sequenceName = "ID_SEQ")
#GeneratedValue(
strategy = GenerationType.SEQUENCE,
generator = "ID")
#Column(name = "ID", updatable = false, nullable = false)
private Long id;
#Column(name = "USER_ID")
private Integer userID;
#Column(name = "HOST_DATE")
private LocalDate hostDate;
#ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
#JoinColumn(name = "Host_DATA_ID")
private POHostData poHostData;
#OneToOne(
mappedBy = "user",
cascade = {CascadeType.ALL})
#JsonManagedReference("Manager_Result")
private ManagerResult ManagerResult;
#OneToMany(mappedBy = "user", orphanRemoval = true, cascade = CascadeType.ALL)
#JsonManagedReference("Basicuser_Authorisation")
private List<Authorisation> authorisation;
#OneToOne(
mappedBy = "user",
cascade = {CascadeType.ALL})
#Valid
private HostLineUser hostLineUser; // for this hostLineUser its showing error
}
And the HostLineUser Entity is
#Getter
#Setter
#NoArgsConstructor
#AllArgsConstructor
#SuperBuilder
#EqualsAndHashCode
#Entity
public class HostLineUser {
#Column(name = "COUNTRY_OF_HOST", length = 2, columnDefinition = "char")
private String countryOfHost;
#Column(name = "HOST_CODE")
private Integer hostCode;
#OneToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "USER_ID", nullable = false)
#EqualsAndHashCode.Exclude
private Employee employee;
}
