The Set Participant Data action in Architect seems to wipe out my custom ivrtokens object on every refresh. I’m passing a JSON string via the Data Action, but when I log the participant state downstream, it’s empty. Here’s the mapping I’m using: {"ivrtokens": {"level": "2"}}. Is there a specific key naming convention or size limit I’m hitting? The webhook endpoint receives the data fine if I push it directly, so the API call works. Just the internal flow variable persistence is failing. My Node.js handler is ready to process it, but the Architect flow keeps dropping the payload.
