I have created a file in INDesign (2025) - it all seems fine on my computer and I have checked in as I normally do by viewing it in the browser, but when sent it to the web developers to upload it to the website (I do this a few times a year) and they have said that they are getting an error:
"viewOpts is not defined" error in the file in5.viewer.js line 11.
I have never had this before and I have exported it twice more using different versions of InDeign including the most up to date 2026 version and they still get the same problem.
