Could not write JSON: For input string: "PARENT"; nested exception is com.fasterxml.jackson.databind.JsonMappingException:

Question

Any hint or help would be greatly appreciated it. I am using Java 17 and jpa with spring boot.

I get the following error: nested exception is

org.springframework.http.converter.HttpMessageNotWritableException: Could not write JSON: For input string: "PARENT"; nested exception is com.fasterxml.jackson.databind.JsonMappingException: For input string: "PARENT" (through reference chain: com.bank.account.model.ChoreEntity["createUserId"]->com.bank.account.model.UserEntity["role"]->com.bank.account.model.RoleEntity$HibernateProxy$LSkoyC50["roleName"])

ChoreEntity.java:

                @JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})
                @ManyToOne(fetch = FetchType.EAGER, optional = false)
                @JoinColumn(name = "create_user_id", nullable = false)
                @OnDelete(action= OnDeleteAction.CASCADE)
                private UserEntity createUserId;

                @JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})
                @ManyToOne(fetch = FetchType.EAGER, optional = false)
                @JoinColumn(name = "assign_user_id", nullable = false)
                @OnDelete(action= OnDeleteAction.CASCADE)
                private UserEntity assignUserId;

                Hibernate: 
                insert 
                into
                chore
                (amount, chore_status_id, create_user_id, name, chore_id) 
                values
                (?, ?, ?, ?, ?)

In this posting: No serializer found for class org.hibernate.proxy.pojo.bytebuddy.ByteBuddyInterceptor

In the ChoreEntity.java I added based on the above stackoverflow: @JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})

In the application.properties file I also added: spring.jackson.serialization.fail-on-empty-beans=false

This error occur after line 36:

Could not write JSON: For input string: "PARENT"; nested exception is com.fasterxml.jackson.databind.JsonMappingException:
