API rollbackBarIndex functionality

Hi,

I'm trying to output the feature tree from a part studio via python - specifically via onshape-client.client.Client.api_client.request(…) (here)

With a standard request, I can output the appropriate response json via the link:

https://cad.onshape.com/api/partstudios/d/34194a7792ea9db6d10188d3/w/2603dadfb9d5ccf8117390d0/e/140112c65afa2d3dddb074ba/features

However, when I include extra parameters (rollbackBarIndex, noSketchGeometry, etc), I can see the response via the link:

https://cad.onshape.com/api/partstudios/d/34194a7792ea9db6d10188d3/w/2603dadfb9d5ccf8117390d0/e/140112c65afa2d3dddb074ba/features?rollbackBarIndex=2&noSketchGeometry=false

but there are 2 problems:

1. the Client.api_client.request runs into a 403 "Resource does not exist, or you do not have permission to access it." This is confusing since I seemingly have access based on the successful response of my initial request. As for my arguments, method='GET', url=the above url, query_params={}, headers={the usual stuff}…
2. the 'rollbackIndex' is defined as '4' in the response (the end of the feature tree) rather than the '2' that I specified. This problem also exists when executing via the glassworks REST API Explorer, indicating that this parameter is ignored:

So what's happening here? Why are these requests being forbidden by the API? Why isn't the rollbackBarIndex being acknowledged? Any help is appreciated!

I just tried, and while I am not seeing a 403, I also see that the rollback bar index parameter doesn't seem to do anything.

What do you need the rollback index for? The definitions of the features shouldn't change when the rollback index is changed.
I know that the rollback index works for other endpoints (such as evaluate featurescript)
