Unable to hear and bots can't hear me

API
1

I have this route endpoint in my app nextJS : // route.ts
import { NextRequest } from ‘next/server’;
import { RealtimeClient } from ‘@openai/realtime-api-beta’;

let client: RealtimeClient | null = null;

async function ensureConnection() {
if (!client) {
if (!process.env.OPENAI_API_KEY) throw new Error(‘OpenAI API key missing’);

client = new RealtimeClient({
  apiKey: process.env.OPENAI_API_KEY,
  model: 'gpt-4o-realtime-preview-2024-10-01',
  instructions: `Vous êtes Superia, l'assistant d'IA générative créé par La Super Agence`,
  voice: {
    enable: true,
    audioResponse: true
  }
});

await client.connect();

client.on('conversation.item.completed', ({ item }) => {
  console.log('Received response:', item);
});

}
return client;
}

export async function POST(request: NextRequest) {
try {
const activeClient = await ensureConnection();
const blob = await request.blob();
const buffer = Buffer.from(await blob.arrayBuffer());
const int16Array = new Int16Array(buffer.buffer, buffer.byteOffset, buffer.length / 2);

await activeClient.appendInputAudio(int16Array);
const response = await activeClient.createResponse();

// Check if we have audio response
if (response?.formatted?.audio) {
  return new Response(JSON.stringify({
    response: response.formatted.transcript,
    audio: Array.from(response.formatted.audio)
  }), {
    headers: { 'Content-Type': 'application/json' }
  });
}

return new Response(JSON.stringify({ 
  response: response?.formatted?.transcript
}), {
  headers: { 'Content-Type': 'application/json' }
});

} catch (error) {
console.error(‘Error:’, error);
return new Response(JSON.stringify({ error: String(error) }), {
status: 500,
headers: { ‘Content-Type’: ‘application/json’ }
});
}
}

The thing is I have no error and I receive in my logs : POST /api/robots/audio 200 in 20ms

But I can’t hear the bots and it can’t hear me, if anyone have ideas.

Thank’s for your support
