Как исправить «Ошибка выполнения DDL «изменение событий таблицы отбрасывает внешний ключ FKg0mkvgsqn8584qoql6a2rxheq» с помощью инструкции JDBC»

Я пытаюсь запустить проект весенней загрузки с базой данных MySQL, но у меня есть проблема с базой данных. Я пытаюсь запустить свое приложение, и сервер работает, но спящий режим не создает таблицы и т. д.

Это мой код:

Пользовательская сущность

 @Entity
   public class User {
      @Id
      @GeneratedValue(strategy = IDENTITY)
      private Long id;

      private String firstName;
      private String lastName;

      private String email;

      private String password;
      private String description;
      private String profile_photo;

      private LocalDate create;
      private LocalDate update;

      @OneToMany(mappedBy = "eventOwner")
      private List<Event> ownedEvents;

           public Long getId() {
    return id;
}

public void setId(Long id) {
    this.id = id;
}

public String getFirstName() {
    return firstName;
}

public void setFirstName(String firstName) {
    this.firstName = firstName;
}

public String getLastName() {
    return lastName;
}

public void setLastName(String lastName) {
    this.lastName = lastName;
}

public String getEmail() {
    return email;
}

public void setEmail(String email) {
    this.email = email;
}

public String getPassword() {
    return password;
}

public void setPassword(String password) {
    this.password = password;
}

public String getDescription() {
    return description;
}

public void setDescription(String description) {
    this.description = description;
}

public String getProfile_photo() {
    return profile_photo;
}

public void setProfile_photo(String profile_photo) {
    this.profile_photo = profile_photo;
}

public LocalDate getCreate() {
    return create;
}

public void setCreate(LocalDate create) {
    this.create = create;
}

public LocalDate getUpdate() {
    return update;
}

public void setUpdate(LocalDate update) {
    this.update = update;
}

public List<Event> getOwnedEvents() {
    return ownedEvents;
}

public void setOwnedEvents(List<Event> ownedEvents) {
    this.ownedEvents = ownedEvents;
}}

Сущность события

   @Entity
   @Table(name = "events")
   public class Event {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;

private Double longitude;
private Double latitude;

private String description;
private String header;

private LocalDate startData;
private LocalDate endData;
private LocalDate creat;
private LocalDate update;
private Filters filters;

@ManyToOne
@JoinColumn(name = "owner_id")
private User eventOwner;

public Long getId() {
    return id;
}

public void setId(Long id) {
    this.id = id;
}

public Double getLongitude() {
    return longitude;
}

public void setLongitude(Double longitude) {
    this.longitude = longitude;
}

public Double getLatitude() {
    return latitude;
}

public void setLatitude(Double latitude) {
    this.latitude = latitude;
}

public String getDescription() {
    return description;
}

public void setDescription(String description) {
    this.description = description;
}

public String getHeader() {
    return header;
}

public void setHeader(String header) {
    this.header = header;
}

public LocalDate getStartData() {
    return startData;
}

public void setStartData(LocalDate startData) {
    this.startData = startData;
}

public LocalDate getEndData() {
    return endData;
}

public void setEndData(LocalDate endData) {
    this.endData = endData;
}

public LocalDate getCreat() {
    return creat;
}

public void setCreat(LocalDate creat) {
    this.creat = creat;
}

public LocalDate getUpdate() {
    return update;
}

public void setUpdate(LocalDate update) {
    this.update = update;
}

public Filters getFilters() {
    return filters;
}

public void setFilters(Filters filters) {
    this.filters = filters;
}

public User getEventOwner() {
    return eventOwner;
}

public void setEventOwner(User eventOwner) {
    this.eventOwner = eventOwner;
}

}

И это мои свойства:

spring.datasource.url= jdbc:mysql://localhost:3306/some_database? 
requireSSL=false&useSSL=false
spring.datasource.username= user
spring.datasource.password= passw 
logging.level.org.hibernate.SQL= DEBUG
spring.jpa.hibernate.ddl-auto = create-drop
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL55Dialect

Это ошибка, которую я получаю

org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing 
DDL "alter table events drop foreign key FKg0mkvgsqn8584qoql6a2rxheq" via 
JDBC Statement

и

Кто-нибудь знает, как это исправить?
