I’m trying to update participant attributes mid-call using the Genesys Cloud Conversations API. The request hits /api/v2/conversations/voice/conversations/{id}/participants/{id} with a PUT method and the JSON payload looks like this: {"attributes": {"queueName": "Support"}}. The response is a 400 Bad Request with the message Invalid input. I’ve checked the attribute name against the schema and it matches. Does the API require the full participant object in the body instead of just the attributes map?
