Controller

$this->validate($request,[ 'import_file' => 'required', ]);

    $db_header_obj = new Voter();
    $db_header = $db_header_obj->getTableColumns();
    $path = $request->file('import_file')->getRealPath();
    $csv = Reader::createFromPath($path, 'r');
        $csv->setHeaderOffset(0); 
        $csv_header = $csv->getHeader(); 

        $sample_data = $csv->fetchOne();
        $sample_data = array_values($sample_data);


    $extension = $request->file('import_file')->getClientOriginalExtension(); 
    $filename = uniqid().'_'.time().'_'.date('Ymd').'.'.$extension;
    Storage::disk('local')->putFileAs('/files/voter/', $request->file('import_file'), $filename);

        $arr = [
            'action' => 'storeCSV',
            'table' => $this->table,
        ];
        $this->storeActivity($arr);

        return view('admin.voter.import_fields', compact( 'csv_header', 'db_header','sample_data','filename'));

What I have tried, with no success

return view('admin.voter.import_fields', compact( 'csv_header'``, 'db_header','sample_data','filename'))->render(); return response()->json(array('success' => true, 'html'=>$returnHTML));
