Laravel: Duplicate column name when there is a groupBy

Why is it that the following error appears when there is a groupBy clause in my query.

Exception Message:\n\nSQLSTATE[42S21]: Column already exists: 1060 Duplicate column name 'id' (SQL: select count(*) as aggregate from (select * from `schools` inner join `dcp_batch_receives` on `dcp_batch_receives`.`school_id` = `schools`.`id` inner join `lib_districts` on `lib_districts`.`id` = `schools`.`district_id` inner join `lib_divisions` on `lib_divisions`.`id` = `lib_districts`.`division_id` group by `schools`.`id`) count_row_table)

This is my query without groupBy and is working correctly.

        $schools = School::join('dcp_batch_receives', 'dcp_batch_receives.school_id', 'schools.id')
        ->join('lib_districts', 'lib_districts.id', '=', 'schools.district_id')
        ->join('lib_divisions', 'lib_divisions.id', '=', 'lib_districts.division_id');

When I add the groupBy it gives the above error.

        $schools = School::join('dcp_batch_receives', 'dcp_batch_receives.school_id', 'schools.id')
        ->join('lib_districts', 'lib_districts.id', '=', 'schools.district_id')
        ->join('lib_divisions', 'lib_divisions.id', '=', 'lib_districts.division_id')
        ->groupBy('schools.id');
