[Haskell-cafe] haskell-ci problems

I am (finally) about to switch my Haskell projects on GitHub from Travis CI to GitHub Actions, so I've tried haskell-ci (from HEAD) for creating the workflow files from the .cabal files. But something went wrong, see https://github.com/haskell-opengl/StateVar/actions/runs/1456427818/workflow Initially, I thought that this failure was related to using the latest and greatest GHC version, so I removed that, but the failure stays: https://github.com/haskell-opengl/StateVar/actions/runs/1456437461/workflow Any hints on what I'm doing wrong? Or is it a haskell-ci bug? Cheers, S.
