I'm seeing these tests fail across PRs targeting branch-24.08:

Environment details

In those failing PRs, I see these relevant versions:

I see the failures across all combinations of Python version, CUDA version, and architecture... and for both wheels and conda packages.

With no investigation, just based on the fact that we're seeing an Index where a Series was expected, I'm going to guess that this is rapidsai/cudf#15833 @mroeschke

[Matthew Roeschke]

Oops sorry opened #1398 to address this

[James Lamb]

Thanks very much @mroeschke !
