            AfterSheet::class    => function (AfterSheet $event) {
                $cellRange = 'A1:W1'; // All headers

            'address'
        ];
    }
}

my controller

public function index(Request $request)

{
 $method = $request->method();
        if ($request->isMethod('get')) {

            $name       = $request->name;
            $email      = $request->email;
            $city       = $request->city;
            $mobile_no  = $request->mobile_no;

            if ($request->has('search')) {
                $dealers = Dealer::where('name', 'LIKE', '%'.$name.'%')
                            ->where('email', 'LIKE', '%'.$email.'%')
                            ->where('mobile_no', 'LIKE', '%'.$mobile_no.'%')
                           ->where('city', 'LIKE', '%'.$city.'%')
                            ->paginate(5);
                return view('dealer.index', compact('dealers'));
            }
            elseif ($request->has('exportSearchExcel')) {
                return Excel::download(new DealersSearchExport($name ?? '', $email ?? '', $mobile_no ?? '', $city ?? ''), 'DealersSearchExcel-reports.xlsx');
            }
            else{
           $dealers = Dealer::orderBy('id', 'DESC')->paginate(5);
            return view('dealer.index', compact('dealers'));
            }
        }
    }

blade

<form action="{{ route('dealer.index') }}" method="GET"  enctype="multipart/form-data">
        @csrf
        <div class="form-group row">
            <div class="col-sm-3">
                <label for="name">Name: </label>
                <input class="form-control" name="name" value="{{ request()->input('name') }}" type="text" placeholder="The Dealer Name">
            </div>
         .....................................................................
            </div>
            <div class="col-md-12 pt-3 text-right">
                <button type="submit" name="search" class="btn btn-primary"><i class="fa fa-fw fa-search"></i> Search</button>
                <button type="submit" name="exportSearchExcel" class="btn btn-secondary text-light"><i class="fa fa-download"></i> Export Excel  </button>                
            </div>
        </div>

No error is showing just in my console it will return this error and download an empty xslx whenever I press the export button.

Update

I fixed it by changing my query in DealerExportSearch.php to the same query that I have in controller then it worked

DealerExportSearch.php

class DealersSearchExport implements FromCollection, WithHeadings, ShouldAutoSize, WithEvents , WithMapping
{
//the above codes not changed till the collection function

    //function select data from database
    public function Collection()
    {
        return Dealer::where('name', 'LIKE', '%'.$this->name.'%')
                            ->where('email', 'LIKE', '%'.$this->email.'%')
                            ->where('mobile_no', 'LIKE', '%'.$this->mobile_no.'%')
                           ->where('city', 'LIKE', '%'.$this->city.'%')
                            ->get();

    }

 public function map($row): array{
           $fields = [
              $row->id,
              $row->name,
              $row->gender,
              $row->date_of_birth,
              $row->email,
              $row->mobile_no,
              $row->shop_name,
              $row->city,
              $row->address,
         ];
        return $fields;
    }


///below codes not changed .....
