API calls failing for Fedora 40, prevents use of rig add

[pj398]

Hi, completely new to rig so may be missing something obvious, but after some trouble with packages not working well with R 4.4 I figured it was a good time to check out rig as I've heard it's a good way to manage multiple R installations.

Unfortunately, I can't get off the ground on Fedora 40 - using rig available or rig add just return the following error (e.g. for rig add 4.3.3):

[ERROR] Failed to resolve R version: Cannot download JSON: HTTP status client error (404 Not Found) for url (https://api.r-hub.io/rversions/resolve/4.3.3/linux-fedora-40/x86_64)

I'm guessing this is because the info for Fedora 40 hasn't been added yet on the server side? If so, is there a timeline on this? I could get around the error for rig available by trying rig available --platform linux-fedora-39 but can't see an equivalent to the platform argument for rig add that would allow me to work around it. Thanks.
