function         


        

Answer 1

Not sure why this would have stopped working, but you might want to try dropping the "getBlob()" part and see if that helps. Documentation suggests the below code should work.

var areaBlob = charts[0].getAs('image/png').setName("areaBlob");

Answer 2

The blank image is due to a sharing permissions issue. Change the share settings of the spreadsheet to "Anyone who has the link can view" and the chart will then be exportable from your script.
