Saving a Pdf/Docx with Aspose failed because of java 17 missing fonts in linux

Question

I convert pdf file to docx on windows with JDK17 and Aspose without any problem. But when I run the same code on Linux I get this error when trying to save a PDF file as Docx using the AsposePDF/AsposeWords 23.5:

java.lang.reflect.InvocationTargetException: java.lang.InternalError

I already tried to run this command in dockerfile as suggested:

rpm install fontconfig

(where does this rpm install these files? seems like the JDK does not contain the fonts anyway)

I also tried to find fonts or fontconfig file on the Linux machine under /usr/lib/jdk and other paths but got no results.

How to handle this issue?
