Curiously enough, autocompletion works, but hover, go-to-definition, etc do not. Happens with and without cradle:

component: "test:cobot-io-test" |

@wz1000 hi, do you have some ideas? I don't even know what additional info should I provide |

I'm not sure, this might be caused by the haskell.nix patches to GHC. I would report this upstream to haskell.nix. In the GHC 8.10.7 source code, this error is only reachable if the |

Thanks! I will raise that issue there. |

Your environment
Which OS do you use:
macOS 11.6 Bug Sur
Which LSP client (editor/plugin) do you use:
neovim + coc.nvim, vs code
Describe your project (alternative: link to the project):
cabal.project + hie.yaml, https://github.com/biocad/cobot-io
Steps to reproduce
I have GHC 8.10.7 from haskell.nix and haskell-language-server 1.7.0.0 built from Hackage with cabal with this patch applied to ghcide: https://github.com/input-output-hk/haskell.nix/blob/master/patches/ghcide-1.7-unboxed-tuple-fix-issue-1455.patch
Expected behaviour
Should work
Actual behaviour
Each file gets this diagnostics:
And nothing works. Adding
-fexternal-interpreterto library's ghc-options does not help.Include debug information
