When I have a template odt and the output format is docx does not work properly.

To replicate this behavior follow these steps.

1. Create a template with format .odt
2. Upload the template
3. Export the template with the output format Docx
4. It gives the error below

   When trying to generate a report from an .odt template to export it as .docx, the report fails and we find the following error in Jira's log:
