u/Exact_Ordinary_9887

To go around the ABI error I run haskell server: haskell-language-server-9.6.7~2.13.0.0

and get this message

Message:

Loading the module

'/home/jacekp/Programming/Haskell/cabal-experiments/graphviz-simple/dist-newstyle/build/x86_64-linux/ghc-9.6.7/graphviz-simple-0.1.0.0/build/autogen/PackageInfo_graphviz_simple.hs'

failed.

It may not be listed in your .cabal file!

Perhaps you need to add `PackageInfo_graphviz_simple` to other-modules or exposed-modules.

For more information, visit:

I can see the example:

Data.GraphViz.Types.Monadic

but I can not figure out the imports and do not understand the error messages.

This is my code so far:
