Doesn't compile for me GHC 8.10.2 when building using cabal:


Building library for casa-types-0.0.1..
[1 of 2] Compiling Casa.Types       ( src/Casa/Types.hs,
dist/build/Casa/Types.o, dist/build/Casa/Types.dyn_o )

src/Casa/Types.hs:52:14: error:
    * Couldn't match expected type `Either String ByteString'
                  with actual type `(ByteString, ByteString)'
    * In the pattern: (result, wrong)
      In a case alternative:
          (result, wrong) | S.null wrong -> pure result
      In a stmt of a 'do' block:
        case Hex.decode (T.encodeUtf8 bytes) of
          (result, wrong) | S.null wrong -> pure result
          _ -> fail "Invalid hex key."
   |
52 |              (result, wrong) | S.null wrong -> pure result
   |              ^^^^^^^^^^^^^^^
cabal: Failed to build casa-types-0.0.1 (which is required by
pantry-0.5.1.3).
See the build log above for details.
