PDF content not visible in OnlyOffice

Hi,

using documentserver 9.0.0 in docker

I have a PDF form template which is loaded to a backend server, some merge fields in the text are updated before sending the updated stream to a browser.

I also write the updated document to a file for testing purposes. The browser stream is requested by OnlyOffice documentserver via a fetch URL and displayed in the PDF editor.

The PDF content displayed in OnlyOffice is good but does not reflect the updates, just the original content. When I open the file which was written by the backend following the updates, in say Linux document viewer, I see the updates. When I open the same file in OnlyOffice the updates are not present?

The updated document looks like this in document viewer;

But looks like this in OnlyOffice;

Any ideas?

The file in question is attached.
