RHEL8 Repo is broken (primary.sqlite is an empty file)

The repo metadata for the RHEL8 CUDA repo is broken and needs regenerating.

http://developer.download.nvidia.com/compute/cuda/repos/rhel8/x86_64/repodata/repomd.xml points to repodata/4755d72e05f47024e53b2ee49ee6914c991941267c14c1ad532fc5b86eb86972-filelists.sqlite.bz2 for a filelist DB.

However this decompresses to a 0B empty file rather than a valid sqlite database, causing repo syncs from the nVidia repository to fail.

I have contacted nVidia Consumer Support already, who sent me here.
