cabal v2-haddock - renderBuildTargetProblem: unexpected status

I have tried to run cabal v2-haddock and I got

cabal: renderBuildTargetProblem: unexpected status (TargetDisabledByUser,Nothing)
CallStack (from HasCallStack):
  error, called at ./Distribution/Client/CmdErrorMessages.hs:329:14 in main:Distribution.Client.CmdErrorMessages

My cabal file is

Do you have any idea, how to solve this problem please?

The project git is https://github.com/stastnypremysl/lsql-csv .

Thanks.

EDIT:

I use Gentoo. Could the problem be caused by missing doc flag in dev-haskell packages?

Solution

I think the error message attempts to tell you that cabal v2-haddock would not build any documentation by default as it contains no libraries. https://github.com/haskell/cabal/issues/6679 tracks error message improvement.
