The documents that fail to convert can be converted on my development environment. They only fail within a timer job, the same code and document works if run from a PowerShell script on the server.

Code to convert the word doc to pdf:
var conversionOptions = new ConversionOptions() { DestinationFileName = destinationFileName };
var pdfOptions = new PdfOptions() { Compliance = PdfCompliance.PdfA1b };
var convertedItem = Converter.ConvertFileToPdf(originalFile, destinationFolder, conversionOptions, pdfOptions);


We suggest you please upgrade to the latest version of Aspose.Words for SharePoint i.e. 18.9 and see how it goes on your end?

In case the problem still remains, please ZIP and upload your input Word document (you are getting this problem with) here for testing. We will then investigate the issue on our end and provide you more information.

Thanks for your response! Technically, it’s not the Aspose version that is wrong, since the same binaries work just fine converting the SAME document outside of a timer job (done from PowerShell on the actual production server). The same document works to convert everywhere except on the production servers and only in the timer-job we have that does it based on an event of our own logic. So the SAME document works to convert in almost all conditions, but not in the actual production condition.


What version of Aspose.Words for SharePoint are you currently using on server machine?

Please ZIP and upload your input Word document (you are getting this problem with) here for testing. Also, please convert the same document to PDF on your development environment and share it here for our reference. What are the operating systems (OS) installed on your development and server machines? We will then investigate the issue on our end and provide you more information

Windows Server 2012 R2
Aspose.Words.SharePoint 17.1.0 (only DLL references, not the full WSP)

TEST Extern tillgång.zip (44.4 KB)

Note: The PDF document is actually converted on the production server, the same server that cannot convert it inside a timer job.
