        if ($validated) {
            $avatar = $this->request->getFile('file');
            $avatar->move(WRITEPATH . 'uploads');
          $data = [
            'name' =>  $avatar->getClientName(),
            'type'  => $avatar->getClientMimeType()
          ];
          // Instantiate an Amazon S3 client.
          $s3Client = new S3Client([
              'version' => 'latest',
              'region'  => 'YOUR_AWS_REGION',
              'credentials' => [
                  'key'    => 'ACCESS_KEY_ID',
                  'secret' => 'SECRET_ACCESS_KEY'
              ]
          ]);
          $bucket = 'YOUR_BUCKET_NAME';
          $file_Path = __DIR__ . '/uploads/'. $filename;
          $key = basename($file_Path);
          try {
              $result = $s3Client->putObject([
                  'Bucket' => $bucket,
                  'Key'    => $key,

          } catch (Aws\S3\Exception\S3Exception $e) {
              //$msg = 'File has been uploaded';
