Hi all. I have started using batch resolvers but I am getting WARN messages in my logs. I have an optional relationship from an encounter to the form_edss (although not marked as optional) that will return nil if there is no corresponding form of that type for the encounter. Tue Nov 30 12:53:38 UTC 2021 WARN :com.wsscode.pathom3.connect.runner/event-batch-unsupported - {:com.wsscode.pathom3.path/path [pc4.rsdb/search-patient-by-pseudonym :t_patient/encounters 3], :com.wsscode.pathom3.connect.operation/op-name com.eldrix.pc4.server.rsdb/encounter->form_edss} From https://github.com/wardle/pc4/blob/49cdaee6031997c3bf1290de25f9df51cacaa4ed/pc4-server/src/com/eldrix/pc4/server/rsdb.clj#L514 : (pco/defresolver encounter->form_edss [{:com.eldrix.rsdb/keys [conn]} encounters] {::pco/input [:t_encounter/id] ::pco/output [{:t_encounter/form_edss [:t_form_edss/id :t_form_edss/edss :t_form_edss/edss_score :t_form_edss_fs/id :t_form_edss_fs/edss_score]}] ::pco/batch? true} (map #(when-not (every? nil?
