[Apiman-user] Apiman 1.2.9 Wildfly - How to capture bodies

Hello, I encounter some errors that don’t throw stack in response. It concern Transformation policy (json ó xml). I have no access to exposed api. To find the root cause, I need to compare inbound and outbound request bodies. Responses bodies could be interesting too. Do you know a method to capture bodies ? Thanks by advance. Best regards.
