Hello,
All DOCX files must have a numbering.xml file. You can solve it using two approaches:
· Add a list in the LibreOffice DOCX to force this program to force the program to create this file.
· Set the DOCX as base template using CreateDocxFromTemplate instead of CreateDocx. Using this class, If there's no numbering file, it will generate a new one.
Both approaches should work fine.
Regards.
