Hi folks, I am trying to integrate reitit with pedestal web backend. For some reason coercion/coerce-exceptions-interceptor is not handling coercion type exceptions. Code: (def router (http/router ["/v1" ["/" {:get {:summary "simple get handler" :parameters {:query {:student-id s/Int}} :handler home-page} :post {:summary "simple post handler" :responses {200 {:body {:total s/Int}}} :parameters {:body {:name s/Str :age s/Int}} :handler home-page}}]] {:exception pretty/exception :data {:muuntaja m/instance :compile rc/compile-request-coercers :coercion reitit.coercion.schema/coercion :interceptors [(parameters/parameters-interceptor) (muuntaja/format-negotiate-interceptor) (muuntaja/format-response-interceptor) (muuntaja/format-request-interceptor) (muuntaja/format-interceptor) (coercion/coerce-response-interceptor) (coercion/coerce-request-interceptor) (coercion/coerce-exceptions-interceptor) (exception/exception-interceptor)]}})) exception: ERROR i.p.http.impl.servlet-interceptor - {:msg "Dev interceptor caught an exception;

Hi. I wanted to use a multimethod but it seems it's not supported?

Execution error (ExceptionInfo) at reitit.exception/exception (exception.cljc:19).
No implementation of method: :expand of protocol: #'reitit.core/Expand found for class: clojure.lang.MultiFn
