Compile error after bumping dependent-sum, dependent-map packages

[dfordivam]

Not sure though if this error is related to these packages or something else.

The reflex-platform now uses dependent-map dependent-map >= 0.3 && < 0.4 after this reflex-frp/reflex@1024703

src/Data/GADT/Aeson.hs:59:22: error:
    • Could not deduce (constraints-extras-0.3.0.1:Data.Constraint.Extras.ArgDict
                          (constraints-extras-0.3.0.1:Data.Constraint.Compose.ComposeC
                             Show f)
                          k)
        arising from the first field of ‘JSONDMap’ (type ‘DMap k f’)
      from the context: (constraints-extras-0.3.0.1:Data.Constraint.Extras.ConstraintsFor
                           k
                           (constraints-extras-0.3.0.1:Data.Constraint.Compose.ComposeC
                              Show f),
                         Data.GADT.Show.GShow k)
        bound by the deriving clause for ‘Show (JSONDMap k f)’
        at src/Data/GADT/Aeson.hs:59:22-25
      Possible fix:
        use a standalone 'deriving instance' declaration,
          so you can specify the instance context yourself
    • When deriving the instance for (Show (JSONDMap k f))
