To Reproduce
Steps to reproduce the behavior:

1. Create a new room.
2. Spawn in an object (e.g. an avatar link or a 3D model, either locally uploaded or from SketchFab, etc.).
3. Open the browser console.
4. See the error.

Expected behavior
An error shouldn't be printed when spawning in an object.

Hardware

• Device: Laptop
• OS: Linux
• Browser: Firefox and Chromium

Additional context
I believe this is the same error I came across when testing media objects for #6338 but now that I'm looking closer I don't think it has anything to do with the issues I was encountering there.
