SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'offset 0' at line 1

My Code:

public function couponList(Request $request){
        $sort_by = $request->get('sort-by');
        $order_by = $request->get('order-by');
        $homeTitle = 'Coupons and List'; 
        $coupons = DB::table('sb_coupons AS CO')
        ->select('CO.*','CO.status as couponStatus','CO.created_at as couponOrderDate','UT.*',
        'UT.firstname as userName')
        ->leftJoin('sb_customer AS UT', 'UT.customer_id', '=', 'CO.user_id');
        if(!empty($request->s)){
            $coupons->Where('CO.coupon_code', 'like', '%' . $request->s . '%');
        }
        if ($request->has('status')) {
            $coupons->where('CO.status', $request->status);
        }
        $coupons = $coupons->paginate(env('RECORD_PER_PAGE'));              
        $coupons->appends($request->s); 

        return view('admin.coupons.coupon-list',array('homeTitle'=>$homeTitle,'coupons'=>$coupons,'params'=>$request, 'sort_by'=> $sort_by , 'order_by' => $order_by))
        ->with('i', ($request->input('page', 1) - 1) * env('RECORD_PER_PAGE'));
    }
