this is expected (and the failure to produce a build plan deliberate).

the current version of hlint requires a ghc-lib-parser-9.8.* these versions of ghc-lib-parser cannot be built by compilers > ghc-9.8 (e.g. ghc-9.12.1).

a future version of hlint (#1629) will upgrade to the ghc-9.12 api. when released, that version will be build compatible with compilers in [ghc-9.8.1, ghc-9.12.1].

haskell.packages.ghc9121: don't test pkgs that don't support 9.12

hlint, ghc-tags and weeder are very much tied to the GHC version or an
appropriate version of ghc-lib and friends, but don't have a release
that supports it yet:
