How to use the rollbar.reportMessage function in rollbar

//       console.timeEnd("pathSave");
        //       processed.resolve({ url: urls.url, thumb: urls.thumb, exif: _exif });
        //     }).fail(function(err) {
        //       processed.reject(err);
        //     });
        //
        //   });


    } else {

      // exif error (doesn't mean that it found anything)
      // rollbar.handleError(result.error, req);
      console.log(result.error);
      console.log(result.error.toString());
      rollbar.reportMessage(result.error.toString(), "debug");

      console.time("s3PathUpload");

      // upload to s3
      s3Upload(file.path, fileType, false).then(function(urls) {
        console.timeEnd("s3PathUpload");
        processed.resolve({ url: urls.url, thumb: urls.thumb, exif: _exif });
      }).fail(function(err) {
        processed.reject(err);
      });

    }
