@embededId containing a foreign key of an entity with inheritance giving an error on bootstraping

Used this as my starting point: https://vladmihalcea.com/the-best-way-to-map-a-many-to-many-association-with-extra-columns-when-using-jpa-and-hibernate/

I have an entity named Attendance that has an and emebedid AttendacneId that has two columns lectureId (string) and studenId(UUID). The attendance entity also has other properties as well containing a ManyToOne relationship with student and lecture enity using the @MapsId on them. The student extends user entity where the id resides. now when I try to save anything I get this error.

My AttendanceId class

My Attendance class

My Student Class

My User class

My Lecture Class
