Can anyone clarify how to retrieve custom participant attributes set via the Web Messaging API inside an Architect Inbound Message flow? I am using a Data Action to map these to the conversation context, but the JSON payload returns null for my custom keys.
The attribute is set correctly during the initial message creation. I verified this by inspecting the raw webhook event. However, when the Get Conversation action runs, the participant object lacks the customData field. Here is the mapping JSON I am using: "value": "${conversation.participants[0].attributes.customKey}".
