Caused by transient Many property .. 
@Entity
public class ETransMany {

    @Id
    Integer id;
    
    String name;
    
    @Transient
    Map<String,String> transMap;

Potential Workaround

A potential workaround is to use the transient modifier

//@Transient
    transient Map<String,String> transMap;
