I am getting error while running group by

Error Code: 1055. Expression #4 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'employees.s.salary' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

SELECT      e.emp_no, e.first_name, e.last_name, s.salary FROM     employees e         RIGHT JOIN     salaries s ON e.emp_no = s.emp_no WHERE     s.salary > 145000 GROUP BY e.emp_no
