Getting System.NullReferenceException while copying the columns from one workbook to other wokbook. This is an intermittent issue, we are using the following piece of code for copying the columns.
upgradingWorkbook.Worksheets[workSheet.Name].Cells.CopyColumns(workSheet.Cells, 0, 0, workSheet.Cells.MaxColumn + 1, new PasteOptions() { PasteType = PasteType.Formats });
please see the below stack trace
