It seems that cabal broke backward compatibility with haskell-language-server or haskell-langauge-server gave a wrong command to cabal.

We're trying to load a completely nonexistent component, so that's bad. @fendor , any thoughts?

[fendor]

Looks like a implicit-hie bug, works fine with a hie.yaml

cradle:
  cabal:

[amano-kenji]

With

cradle:
  cabal:

as hie.yaml, I can work around the issue, too.

[amano-kenji]

I don't have stack on my system, but beam has stack.yaml. Is that why implicit-hie failed?

[fendor]

We currently don't know why implicit-hie fails, or why your binary has been built with the affected version of implicit-hie 0.1.3.0, since we have explicitly forbidden that version.

[amano-kenji]

My gentoo linux system currently has dev-haskell/implicit-hie-0.1.2.7

[fendor]

Reading the report, this does not have to be necessarily connected to the broken release of implicit-hie but an entirely different bug. You can try to reproduce it on the cli by installing the accompaying binary gen-hie (should be part of implicit-hie) and running it in your project and inspecting the produced hie.yaml.

Yeah, it seems to be a bug in implicit-hie. It looks like, implicit-hie thinks here is an internal library for some reason.
