Hello,
Thank you for your feedback.
Based on the information you provided, I have tested your Word document in a Docker environment, but I was unable to replicate the issue you mentioned. Please verify that the parameter value "file.getRef().path().toString()" in your project is correct.
Also, need to check with you to see if the documentation that reported the error in your project group matches what you provided to us.
Sincerely,
Annika
