this is expected (and the failure to produce a build plan deliberate).
the current version of hlint requires a ghc-lib-parser-9.12.* these versions of ghc-lib-parser cannot be built by compilers > ghc-9.12 (e.g. ghc-9.14.1).
a future version of hlint (#1629) will upgrade to the ghc-9.14 api. when released, that version will be build compatible with compilers in [ghc-9.10.1, ghc-9.14.1].
