Steps to reproduce

Follow the below steps to reproduce this error:

1. Create a Microsoft Word template.        
2. Use the OOTB Generate Document shape in the template or call the pxGenerateAndAttachDocument activity within the case flow.
3. Process the case to the point where the document is generated and attached.
4. Download and open the document.

Root Cause

There is a problem with the docx4j library version used in the Pega Platform. The error occurs due to Pega's docx4j library not declaring the “w16du” namespace, which is required by Microsoft Word.

Solution

As a workaround:

1. Apply HFIX-B2415 to remediate this error in Pega Platform™ 23.1.1. 
2. Apply HFIX-B2329 to remediate this error in Pega Platform 8.8.5. Versions 8.8.3 and 8.8.4 must update to Pega Platform 8.8.5 and apply HFIX-B2329 to remediate the issue. 
3. Apply HFIX-B2515 to remediate this error in Pega Platform 8.7.6. 

HFIX-B2415, HFIX-B2329, and HFIX-B2515 updates Pega’s docx4j library version to docx4j 8.3.10 which resolves the error.
