Hi,

I am using POI 4.1.1 and latest Excel format (Office 365 Excel version : 16.39). My Excel sheet has cells with some comments in it, when I try to clone this sheet it fails with following error. Can you please suggest a solution for this.

Exception in thread "main" org.apache.poi.ooxml.POIXMLException: Can't clone sheet - unknown relation type found: http://schemas.microsoft.com/office/2017/10/relationships/threadedComment

public static void main(String[] args) throws Exception {
        Workbook workbook = WorkbookFactory.create(new FileInputStream("Sample.xlsx"));

        Sheet cloned = workbook.cloneSheet(0);

        System.out.println("Clone Successful : "+ cloned);
    }
