in the Stackage Nightly build

test/Web/Spock/FrameworkSpecHelper.hs:31:25: error:
    • Couldn't match expected type ‘MatchBody’
                  with actual type ‘Maybe a’
    • In the ‘matchBody’ field of a record
      In the expression:
        ResponseMatcher
          {matchStatus = s, matchBody = Just b, matchHeaders = []}
      In an equation for ‘matcher’:
          matcher s b
            = ResponseMatcher
                {matchStatus = s, matchBody = Just b, matchHeaders = []}

test/Web/Spock/FrameworkSpecHelper.hs:170:12: error:
    • Couldn't match expected type ‘Body -> Maybe String’
                  with actual type ‘Maybe [Char]’
    • Possible cause: ‘loop’ is applied to too many arguments
      In the expression: loop relevantHeaders
      In the expression:
        let
          relevantHeaders = filter (\ h -> fst h == "Set-Cookie") headers
          loop []
            = Just

                 ++ T.unpack name ++ " with value " ++ T.unpack val ++ " found")
          loop (x : xs) = let ... in ...
        in loop relevantHeaders
      In the second argument of ‘($)’, namely
        ‘\ headers
           -> let
                relevantHeaders = ...
                ....
              in loop relevantHeaders’

Thank's I'll take a look at it.
