Assistant's Messages Are Being Wiped
Author: egyptianego17Created Oct 9, 2025Updated Oct 9, 2025
I'm using OpenAI Realtime Agents with Twilio. I'm initializing the agent with basic instructions:
return new RealtimeAgent({
name: 'Twilio Voice Assistant',
instructions: this.systemMessage,
tools: [],
});I then read the call information, get the corresponding agent, and update the agent:
await session.updateAgent(agent);
While using the agent, I noticed that it was repeating messages. I started tracing the history through:
console.log('Session History:', JSON.stringify(session.history, null, 2));
I found that the assistant's message is being deleted when a new one appears. Please check the sequence below.
