JPA Issues #OneToMany(MappedBy) - spring

Question

I have this issue with these models in my project and I don't know what is the issue exactly with these two models and these two realationships in Data JPA Car Model Below:
package com.wq.v1.domain.model;
import com.fasterxml.jackson.annotation.JsonIgnore;
import com.fasterxml.jackson.annotation.JsonProperty;
import lombok.Getter;
import lombok.Setter;
import javax.persistence.*;
import java.io.Serializable;
import java.util.Set;
#Entity
#Table(name = "cars")
#Getter
#Setter
public class Car implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(nullable = false, updatable = false)
#JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
private long id;
#ManyToOne
#JoinColumn(name="firm_id", nullable=false)
private Firm firm;
#OneToOne(cascade = CascadeType.ALL)
#JoinColumn(name = "driver_id", referencedColumnName = "id")
private Driver driver;
#Column(name = "car_type")
private String car_type;
#Column(name = "car_model")
private String car_model;
#Column(name = "car_plate")
private String car_plate;
#Column(name = "car_owner")
private String car_owner;
#OneToMany(mappedBy="cars")
#JsonIgnore
private Set<Image> images;
#OneToMany(mappedBy="cars")
#JsonIgnore
private Set<Docs> docs;
public Car(){
}
public Car(Firm firm, Driver driver, String car_type, String car_model, String car_plate, String car_owner, Set<Image> images, Set<Docs> docs) {
this.firm = firm;
this.driver = driver;
this.car_type = car_type;
this.car_model = car_model;
this.car_plate = car_plate;
this.car_owner = car_owner;
this.images = images;
this.docs = docs;
}
}
And this is the Docs model:
package com.wq.v1.domain.model;
import com.fasterxml.jackson.annotation.JsonProperty;
import lombok.Getter;
import lombok.Setter;
import javax.persistence.*;
import java.io.Serializable;
#Entity
#Table(name = "docs")
#Getter
#Setter
public class Docs implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(nullable = false, updatable = false)
#JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
private long id;
#ManyToOne
#JoinColumn(name = "driver_id", nullable = false)
private Driver driver;
#ManyToOne
#JoinColumn(name="car_id", nullable=false)
private Car car;
#Column(name = "nat_id", columnDefinition = "LONGTEXT")
private String nat_id;
#Column(name = "passport", columnDefinition = "LONGTEXT")
private String passport;
#Column(name = "driver_license", columnDefinition = "LONGTEXT")
private String driver_license;
#Column(name = "resd_id", columnDefinition = "LONGTEXT")
private String resd_id;
#Column(name = "resd_permit", columnDefinition = "LONGTEXT")
private String resd_permit;
#Column(name = "car_register", columnDefinition = "LONGTEXT")
private String car_register;
#Column(name = "disclaim", columnDefinition = "LONGTEXT")
private String disclaim;
#Column(name = "trans_autho", columnDefinition = "LONGTEXT")
private String trans_autho;
public Docs(){
}
public Docs(Driver driver, Car car, String nat_id, String passport, String driver_license, String resd_id, String resd_permit, String car_register, String disclaim, String trans_autho) {
this.driver = driver;
this.car = car;
this.nat_id = nat_id;
this.passport = passport;
this.driver_license = driver_license;
this.resd_id = resd_id;
this.resd_permit = resd_permit;
this.car_register = car_register;
this.disclaim = disclaim;
this.trans_autho = trans_autho;
}
}
And finally this is the error:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Invocation of init method failed; nested exception is org.hibernate.AnnotationException: mappedBy reference an unknown target entity property: com.wq.v1.domain.model.Docs.cars in com.wq.v1.domain.model.Car.docs

I searched a lot a tried many ways to fix it and didn't work even here I found a lot of questions without solving in here.
