Stream transcript events over Server-Sent Events (Content-Type: text/event-stream), not a single JSON response. Events are connected, turn, and ended; heartbeat comments keep the connection alive. The published TypeScript SDK 1.0.25 does not parse this stream correctly. Use these HTTP examples and the streaming guide until a corrected SDK is released.
