Join two JPA bidirectionally having same col names?

Question

I've two table

    @Entity
    @NamedEntityGraph(name = "one", attributeNodes = {@NamedAttributeNode("two")})
    @Table(name = "one")
    One.class {

   @Id
    private sno;
    
    private String version;
    
    @Column(name = "bgn_no")
    private String bgnNo;

    @OnetoOne(cascade = CascadeType.All, fetch = FetchType.EAGER)
    @JoinColumn(name = "bgn_no", referenceColumnName = "bgn_no", insertable = false, updatable = false)
    private Two two;
    
    
    }
    
    @Entity
    @Table(name = "two")
    Two.class {

   @Id
    private dim_no;
    
    @Column(name = "bgn_no")
    private String bgnNo;
    
    private location;
    private region;

    @OneToOne(mappedBy = "two")    -> issue
    private One one;               -> issue
    
    }

repository

BGNRepository extends PagingAndSortingRepository<One, String> {

    @EntityGraph(value = "one")
    One finfbyBgnNo(String no);

}

calling above repository using servcieBGNRepository.finfbyBgnNo(String no, String ver)

There are some other columns too in entities, but am joining on the basis bgn_no col. This col is present in both tables with same names. Above repository works fine only when -> issue lines are removed from above code, else giving below error

Getting error

Error Accessing field (private Two.bgn_no] by reflection for persistent property [Two#bgn_no], nested exception is org.hibernate.property.access.spi.PropertyAccessException: Error accessing field [private  Two.bgn_no ] by reflectionfor persistent property[ Two#bgn_no]

I'm literally stuck on this issue. Can anyone suggest what can be done. I've tried adding getter/setter too. But still same issue.
