+With Grape v1.3+, Array types must be defined with a `coerce_with`

 ## Using HTTP status helpers
 
 For non-200 HTTP responses, use the provided helpers in `lib/api/helpers.rb` to ensure correct behavior (`not_found!`, `no_content!` etc.). These will `throw` inside Grape and abort the execution of your endpoint.
