The given key was not present in the dictionary

Hi,

I have a pdf file which has 29 pages. First 28 pages are of normal pages size while page 29 is of different size. I have a code snippet that imports all pages one by one from this pdf file into other multiple pdfs. The code works fine untill it comes to the page 29. At this point when importing, it throws following exception:

The given key was not present in the dictionary.
at System.ThrowHelper.ThrowKeyNotFoundException()
at System.Collections.Generic.Dictionary`2.get_Item(TKey key)
at Syncfusion.Pdf.PdfDocumentBase.ExportBookmarks(PdfLoadedDocument ldDoc, List`1 bookmarks, Dictionary`2 pageCorrespondance, Dictionary`2 bookmarkshash)
at Syncfusion.Pdf.PdfDocumentBase.ImportPageRange(PdfLoadedDocument ldDoc, Int32 startIndex, Int32 endIndex)
at Syncfusion.Pdf.PdfDocumentBase.ImportPage(PdfLoadedDocument ldDoc, Int32 pageIndex)
at Syncfusion.Pdf.PdfDocumentBase.ImportPage(PdfLoadedDocument ldDoc, PdfPageBase page)


Please note that I am using Syncfusion v7.4. Is this a known issue?

Thanks,
Khalid
