Uncaught TypeError: Illegal invocation

[nargiskhatoon]

Hi
I am getting this error "abc.js, Uncaught TypeError: Illegal invocation" on this line "fileReader.readAsArrayBuffer(slicer.call(file, start, end));",

code:

.
.
.
  $scope.hashFile =  function () { 
    fileMd5Service.md5($rootScope.fileObj)
      .progress(function (stats) {
        console.log('Hashed ' + stats.loaded + ' B out of ' + stats.total + ' B');
      })
      .error(function (error) {
        console.log('Error calculating md5: %o', error);
      }).success(function (md5sum) {
        console.log('MD5 for ' + $rootScope.fileName + ' is ' + md5sum);
      });
  };

Please Help, Thanks
