Image is not getting uploaded to s3, it did but file is not opening

ionic-v1

yeah, i missed step to making blob out of base64 image file.

now its working. here is sample code.

// boilerplate function to create a Blob
	$scope.dataURItoBlob = function(dataURI) {
	  var binary = atob(dataURI.split(',')[1]);
	  var array = [];
	  for (var i = 0; i < binary.length; i++) {
	    array.push(binary.charCodeAt(i));
	  }

	  var mimeString = dataURI.split(',')[0].split(':')[1].split(';')[0];
	  return new Blob([new Uint8Array(array)], {
	    type: mimeString
	  });
	}
		 
	$scope.upload = function(imageURI) {
	  // Configure The S3 Object 
	  AWS.config.update({ 
	  	accessKeyId: $scope.creds.access_key, 
	  	secretAccessKey: $scope.creds.secret_key 
	  });
	  /*AWS.config.region = 'us-east-1';*/
	  var bucket = new AWS.S3({ params: { Bucket: $scope.creds.bucket } });
	 
	  if(imageURI) {
	  	var data = $scope.dataURItoBlob(imageURI);

	    var params = { 
	    	Key: $scope.guid + '/' + 'profileImg.jpg',
	    	ContentType: 'image/jpeg',
	    	Body: data,
	    	ACL: "public-read",
	    };
	 	
	    bucket.putObject(params, function(err, data) {
	      if(err) {
	        // There Was An Error With Your S3 Config
	        //console.log("THIS ERROR:", err);
	        return false;
	      }
	      else {
	        // Success!
	        $scope.data.profileImg = imageURI;
	        $scope.$digest();
	        window.localStorage.profileImg = $scope.data.profileImg;
	        /*alert('Upload Done');*/
	      }
	    })
	    .on('httpUploadProgress',function(progress) {
	          // Log Progress Information
	          //console.log(Math.round(progress.loaded / progress.total * 100) + '% done');
	        });
	  }
	  else {
	    // No File Selected
	    //alert('No File Selected');
	  }
	}
