Recently We have upgraded our App with Licensed Aspose latest version – 21.9 for applying Watermark on the Excel files.
But, It has been observed that with this latest Aspose version few of the XLSX files are not getting watermarked and its throwing “ArrayIndexOutOfBoundsException” but same files with older version – 8.9.0 (which we were using earlier) are perfectly getting watermarked.
while saving i am getting this exception.
please help me how i can resolve it with version 21.9
Note - Ideally the latest version should be compatible with the older version fixes but it looks this is not the case with latest Aspose version- 21.9
