`setup` emits invalid `outputs.cabal-store`
I'm getting warnings about caching failing to save, due to an invalid path. The path is being set by steps.setup.outputs.cabal-store.
With this step in my workflow file:
# Cache dependencies already here, so that we do not have to rebuild them should the subsequent steps fail.
- name: Save cached dependencies
uses: actions/cache/save@v3
# Caches are immutable, trying to save with the same key would error.
if: ${{ steps.cache.outputs.cache-primary-key != steps.cache.outputs.cache-matched-key }}
with:
path: ${{ steps.setup.outputs.cabal-store }}
key: ${{ steps.cache.outputs.cache-primary-key }}
I get this warning in my action logs:

The location of the cabal store may have changed recently? Not sure.

I get this warning in my action logs:
This link is expired. Do you have a valid link to the failing log? Of interest is e.g. the version of the VM this workflow ran on.
The issue could be caused by a new location of .cabal/store thanks to the XDG adoption in cabal 3.10: https://github.com/haskell/cabal/issues?q=is%3Aissue+label%3A%22re%3A+xdg%22
