Quick question about IVR JSON payload mapping

Quick question about mapping Zendesk ticket fields to Genesys IVR parameters. The Architect flow fails at the Set Interaction Data block with a 400 Bad Request when sending the JSON payload.

Environment details:

  • Genesys Cloud version: 2024-10
  • Zendesk Export: CSV to JSON via Python script
  • Architect Flow: Standard IVR with Data Set block

The JSON structure matches the schema, but the validation fails on the custom_fields array. Is there a specific format requirement for nested objects in the IVR data set?
