DocumentInfo in CustomDataInputHandler



i’ve implemented a custom inputdatahandler for our dms using an uuid to identify the file. Loading and converting the documents using handler.getPages(uuid) works fine, but when i try to get the documentinfo using handler.getdocumentinfo(uuid), i get the following exception.

class guid should contain file extension
com.groupdocs.viewer.handler.ViewerHandler.getDocumentInfo(Unknown Source)

Hello ,

Could you please specify , which version of the GroupDocs.Viewer for Java library you are using? Also could you please share with us your CustomInputDataHandler code .

We will wait for your details.
