Which version of ThreeJS do I need for my object-loader to work?


I created a little 3d-model in Spline, and I exported it to web. I know that the scene.json can be loaded through the Object-Loader but I am not sure which version of Threejs is compatible.
The metadata of the object is this:

    "version": 1.5,
    "type": "Object",
    "generator": "Object3D.toJSON"

I tried the newest version of threejs and it doesn’t work, is there a correct version?
