The stack resolver version for Haskell on the Redis track is quite old. Could it be updated to LTS 23.18? Is there a way to perhaps adopt/inherit the resolver version set in the local `stack.yaml`?

Hey @OlaoluwaM, our tester does use your local stack.yaml, but it looks like the Haskell version on our end is a bit out of date.

I’ll work on updating the Haskell buildpack and will let you know once that’s done.

@OlaoluwaM I’ve upgraded the Haskell buildpack for Redis to **v9.8.4** and pushed a couple of commits to your repo. You can run git pull to start using the new resolver: **lts-23.18**.

Let me know if you run into any issues!
