My Error

My Callback function

$problem_condition_computations = function($condition) use ($psrm_maintenance, $start, $end, $customers){
        return DB::table('liip_psrm')
        ->join('liip_psrm_items', 'liip_psrm.id', '=', 'liip_psrm_items.psrm_items_id')
        ->whereDate('liip_psrm_items.created_at', '>=', $start)
        ->whereDate('liip_psrm_items.created_at', '<=', $end)
        ->select(
                DB::raw("DATE_FORMAT(liip_psrm_items.created_at, '%Y-%m-%d') AS dates
                "))
                ->where('liip_psrm.status','=', 0)
                ->where('liip_psrm.customer_id','=',$customers)
                ->where('pallet_condition', $condition)
                ->groupBy('dates')   
                ->count();
      };

"dates" field you are using in groupBy is alias name, So it do not identifying it and not working as you are expecting.

Same as you used in Select 

DB::raw("DATE_FORMAT(liip_psrm_items.created_at, '%Y-%m-%d') AS dates")

Put it in GroupBy & It will work.

Hope, It will help, Let me know if you still find difficulties.
