We have an existing workflow built on Nintex 2013 (SharePoint on-prem) and using Workflow action - Update document to create new word document using content controls with the content from list item. we have a column with multi-line text for summary and when the character limit on the text exceeds like 4500 characters, workflow breaks at the Update document step and says Incomplete. this happens only if the text is longer if not, workflow works fine. so is there a limitation with length of the text when creating new word document with Nintex workflow?
The Convert Document relies on Microsoft Word Services.
Try to use the service outside a workflow to confirm it is fully functional in the same way you want to use it inside the Nintex workflow.
