DOC to PDF conversion issue

[atirtahirgroupdocs]

This issue is raised in https://forum.groupdocs.com/t/doc-to-pdf-conversion-issue-in-linux-using-java/8492
Hi,
You can reproduce this issue in Linux (tested on following flavors):

• Red Hat Enterprise Linux Server - Version: 7.0
• Ubuntu 19.10

Issue Details: Whenever I convert any DOC file to PDF, it says conversion is done, but no output is generated (there is no error or exception either). When I try to download the output file from the application, nothing happens (conversion/converted folder is always blank).
Please have a look at this screencast.
However, DOC to image, XLSX to DOC conversion works fine, I get the converted output.

Please take a look.
Thanks
