Can anyone please help ?

Which viewer version are you using?? Type `LMV_VIEWER_VERSION` in your browser console will tell. — Eason Kang, Dec 07 '17 at 10:04

This problem may be caused by the use of an outdated version of the viewer.

Currently the Viewer is on Version 3.3 I will suggest doing the migration to solve your problem and also take advantage of all the new functionality.

Here is a list of the changelogs https://developer.autodesk.com/en/docs/viewer/v2/overview/changelog/

And here the blog post about the newer version https://forge.autodesk.com/blog/viewer-release-notes-v33
