springframework.validation.BindException: Date

public class ReservationForm {
    @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm")
    private LocalDateTime date;

    public ReservationForm(LocalDateTime date) {
        this.date = LocalDateTime.now();
    }

    public LocalDateTime getDate() {
        return date;
    }

    public void setDate(LocalDateTime date) {
        this.date = date;
    }

}

public class ReservationForm {
    @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm")
    private LocalDateTime date;

    public ReservationForm(LocalDateTime date) {
        this.date = LocalDateTime.now();
    }

    public LocalDateTime getDate() {
        return date;
    }

    public void setDate(LocalDateTime date) {
        this.date = date;
    }

}

what i want: datepicker sends ajax request on changing the date to reload the displayed data, but when i change the date an error is thrown. demo project to showcase my problem: https://github.com/DragonCat4012/web-thymeleaf
