Hello,

Thanks for your reply, I am using the latest Aspose.Words for reporting Services 19.2
I have narrowed down to this specific problem.
If I remove the image from the RDLC the export export functions for Aspose start working, but with the image the export throws the exception.
Please check the attached RDLC
