CoerceValidator broken by major release of virtus-1.0.0

[JimGaylard]

I was having trouble with a Grape app after a bundle update. Turns out virtus updated from 0.5.5 to 1.0.0 very recently and the Changelog lists a breaking change.

I checked out Grape and ran the test suite and it's failing on the CoerceValidator.

I haven't had time to work out a fix but wanted to report it. I've explicitly locked virtus at 0.5.5 in my Gemfile and the tests are all passing so I'm pretty confident that's what is causing it.

We should upgrade virtus in Grape dependencies and make whatever fixes are needed.
