Hey 
What specifically is not visible? All of it? The object and the UI?
If you place a cube, is that exported correctly?
object. Yes. The camera itself sees the object

i still don’t follow, could you screenshot the browser? Is the cube visible?
could you screenshot your camera settings?
Do you have any errors in the console? Both in the unity console and in the browser console? (screenshots if something questionable)

what is npm def object ?
by user 1101049107931480066
That is an npm module containing logic, it is great way how to structure and reuse code.
You don’t need to do that tho
and what do I need to do?

Can you try to disable the gameobject called canvas? It might be rendering on top hiding your content
turned off.
Yes, it is displayed, but for some reason the UI Canvas overlaps it
