Error handling bigdecimals into payload. #435

Problem

I tried to include a middleware to deal with bigdecimals data type in my payload by using:

(context "/contracts" []
    :middleware [wrap-json-body {:bigdecimals? true}]
    (resource
     {:tags ["assignments"]
      :coercion :spec
      :post {:summary "inform contract offers"
             :parameters {:body-params ::contracts/spec}
             :handler (fn [{contracts :body-params}]
                        (let [opid (core/launch-processing contracts/process-offers contracts :contract)]
                          (ok {:operation-id opid})))}}))

However, I get this stack trace:
