Question
PDF from Single DOCX (with Fonts) Issue
We are facing issues with PDF from Single DOCX plugin when generating a PDF doc form DOCX. This plugin is working whit out any issues until 21.2 Version. We recently upgraded one environment to Appian latest version 21.3. After this upgrade the PDF from Single DOCX (with Fonts) smart service is breaking when generating document. The same DOCX document we will be able to convert in other environments(21.2). We are not sure what is the root cause. Could any one know the root cause for this issue.
The following is the log error from the tomcat-stdOut.log
