Reported error when setting values in an Excel File.
'Excel Services Application setting does not allow the requested operation to be performed.'
The same JavaScript runs correctly in SharePoint Online, but of course that is running Version 16.
What configuration in the Excel Services Service Application will permit execution of this JavaScript:
var range = ewa2.getActiveWorkbook().getRange("Sheet2",1,1,1,40);range.setValuesAsync(values,setRangeCallback,null);
