Query Dsl NumberPath as operation not working

DSL query NumberPath as an operation does not work. below is the code

    BooleanBuilder whereClause = new BooleanBuilder();
    if(columnType!=null && columnType.equalsIgnoreCase("Long")){
                Number searchNumb= (Number)filterMap.get("searchText");
                Long searchText=searchNumb.longValue();
                NumberPath<Long> longColumn = 
                Expressions.numberPath(Long.class,query,searchType);
                whereClause.and( longColumn.like("%"+searchText+"%") );
    }
    return logRepository.findAll(whereClause, pageable);

      

        
        
        
      

    

below is the generated sql log

but when I run the generated sql with the binding value on PGAdmin it gives the result. Below sql I was running PgAdmin.

select count(commonlog0_.id) as col_0_0_ from common_log commonlog0_ where 
 cast(commonlog0_.process_id as varchar) like '%164%' escape '!'
