Bulk Import is not working with some PDF files.

Hi,

 

I'm having the follwing error when trying to import an uploaded PDF file to Bulk Import. The exception only happens with some files and working well with the others. Please let me know your email so I can send the PDF file that I have used.

Error: is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at org.pdfbox.pdmodel.PDPageNode.getCount() at org.pdfbox.pdmodel.PDDocument.getNumberOfPages() at GenePdf..ctor(String PathPdfSource, String Path, String PathDestMM, String PathExeMM, Int32 portalId, PortalSettings portalSettings, String large) at ThreadParams..ctor(Int32 portalId, PortalSettings portSettings, String LocalFile, String ctrlZipUrl, Boolean overwrite, String monFileName, String TemplateSourceDirectory, Int32 ModuleId, String PathexeMM, Boolean cbZipContainManifestChecked, Boolean cbLabelIsFileNameChecked, Boolean cbLargeFileDiscoverChecked, Boolean cbAllTearOff, String tbLargeFileNameAdditionTextToString, PageFlipSettingsInfo objSettings, PageFlipXMLHelper objPageFlipXMLHelper) at Aricie.DNN.Modules.PageFlip.Import.cmdImportAndOverwrite_Click(Object sender, EventArgs e) --- End of inner exception stack trace ---

 

Thanks,
