eve crashes on malformed sort parameters

[NotSpecial]

When sending a malformed sorting parameter to eve, it should return 400 for bad request.
Instead, eve crashes and returns a 500.

This can be reproduces with the demo app:

This works:

curl "http://eve-demo.herokuapp.com/people?sort=firstname"

This crashes with 500, instead of returning 400:

curl "http://eve-demo.herokuapp.com/people?sort='firstname'"

Is there any way to fix this?

Thank you for the fast resolution 👍
