@inceptionEhv,

Saving your DOCX Word document to PDF format after updating the Fields causes a java.lang.NullPointerException on our end:

Document doc = new Document("C:\\Temp\\document\\Nullpointer exception.docx");
doc.updateFields();
doc.save("C:\\temp\\document\\awjava-20.9.pdf");

For the sake of correction, we have logged this problem in our issue tracking system. The ID of this issue is WORDSNET-21121. We will further look into the details of this problem and will keep you updated on the status of correction. We apologize for your inconvenience.
