loading gltf objects into R3F

[jskye]

i couldnt get the grass or rabbit gltf objects to load.

following these examples

Uncaught Could not load ./assets/grass/grass.gltf: JSON.parse: unexpected character at line 1 column 1 of the JSON data

badly formed json?
related?

edit: tried another model and same problem, so models not the problem. must be the way its loading.
after loading json error, browser reports the webgl context is lost.
