File upload in an array not work

Dear Friends, I am trying to upload PDF file(s) through a dynamic upload field . The file name is stored but physical file is not stored in folder. my code is

 $uploads = $request->file('uploadworkexperience');
            foreach ($organizations as $key => $organization) {
                $data = [
                  'app_id' => $app_id,
                  'exp_organisation' => $organization,
                  'exp_designation' => $designations[$key],
                  'exp_job_role' => $jobroles[$key],
                  'exp_responsibilities' => $responsibilities[$key],
                  'exp_work_from' => $fromdates[$key],
                  'exp_work_to' => $todates[$key],
                  'exp_certificate' => $uploads[$key]->storeAs('public/work_experience', $uploads[$key]->getClientOriginalName(), ['force' => true])
                ];
                DB::table('ksitm_work_experience')->insert($data);
              }

$uploads array is like

array:2 [ // app\Http\Controllers\ApplicantController.php:210
  0 => Illuminate\Http\UploadedFile {#284
    -test: false
    -originalName: "sample.pdf"
