Compile failure

This is most likely caused due to missing or inaccurate version bounds:

I'm not quite sure how to fix this. I tested with ghc 8.0. I tried building on ghc 7.10, and got the error you showed me. Can it be fixed with a constraint? The wai version seems to be the same between the two stackage lts versions.

@seanhess as it seems you're using Stack, I think the simplest proper way would be to add pvp-bounds: both (see docs here) to your stack.yaml file, and use (mostly) the version bounds inferred from the stackage snapshot used.

I've emulated more or less what pvp-bounds: both does with the help of staversion (as I don't have Stack installed), and after some trial & error and tweaking the bounds, I came up with the following bounds which I've already revised into the affected release:

  build-depends:
      aeson >=1.0.2.1 && <1.3
    , binary >=0.8.3 && <0.9
    , bytestring >=0.10.6 && <0.11
    , http-types >=0.9.1 && <0.10
    , text >=1.2.2.1 && <1.3
    , wai >=3.2.1.1 && <3.3
    , base >=4.8 && <5

And now it's all green at https://matrix.hackage.haskell.org/package/wai-middleware-json-errors
(but note that GHC 7.8.4 support had to be dropped, as the source code assumes a post-AMP prelude; but it's no big deal; GHC 7.8.4 is quite old by now).

Great, thanks for your help! I just added pvp-bounds: both, and uploaded 0.1.1. Let's see if it works.
