[Object object] response using Assistants APi with Node.js

Hello, everyone.

I’m currently facing an issue trying to display the chat responses of the Assistant I created. While the console displays a 200, the frontend displays [Object object]. I’ve debugged many sections of the code and I can’t seem to find the problem. Any help would be appreciated:

Assistant Code:

// src/pages/api/ask.js
import OpenAI from ‘openai’;

// Initialize OpenAI client
const openai = new OpenAI({ apiKey: ‘■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■1wHQWrNz’ });

export async function POST({ request }) {
try {
// Parse the request body to get the question
const { question } = await request.json();

console.log("question: ", question);

const run = await openai.beta.threads.createAndRun({
    assistant_id: 'asst_dqbm31oKzZqFGHTIIEzcnSLM',
    thread: {
        messages: [
            {
                role: 'user',
                content: question
            }
        ]
    }
})

console.log("run thread_id: ", run.thread_id)
console.log("run: ", run)

let runStatus = run.status;
while (runStatus !== 'completed' && runStatus !== 'failed') {
// Esperar un tiempo antes de volver a comprobar el estado
await new Promise(resolve => setTimeout(resolve, 5000));

// Comprobar el estado de la ejecución
const runCheck = await openai.beta.threads.runs.retrieve(
    run.thread_id,
    run.id,
);
runStatus = runCheck.status;
}

if (runStatus === 'failed') {
    throw new Error('Run failed');
}

// Retrieve the list of messages, which now includes the assistant's response
const messages = await openai.beta.threads.messages.list(
  run.thread_id
);

console.log("list of messages: ", messages.data)

// Filter out only the assistant's responses
const assistantMessages = messages.data.filter(msg => msg.role === 'assistant');

// Return the assistant's latest response
return new Response(JSON.stringify({
  status: 'success',
  data: assistantMessages[assistantMessages.length - 1]
}), {
  status: 200,
  headers: {
    'Content-Type': 'application/json'
  }
});

} catch (error) {
console.error(‘Error interacting with OpenAI Assistant:’, error);
return new Response(JSON.stringify({
status: ‘error’,
message: ‘Failed to process your request’
}), {
status: 500,
headers: {
‘Content-Type’: ‘application/json’
}
});
}
}

Frontend call:

// Assistant
document.getElementById(‘sendBtn’)?.addEventListener(‘click’, sendMessage);
document.getElementById(‘messageInput’)?.addEventListener(‘keypress’, function (e) {
if (e.key === ‘Enter’) {
sendMessage();
}
});

    async function sendMessage() {
        const input = document.getElementById('messageInput') as HTMLInputElement; // More specific type
        if (!input || input.value.trim() === '') return; // Check if input is not null and prevent sending empty messages
        const messageContent = input.value.trim();
        input.value = ''; // Clear input field

        displayMessage(messageContent, 'right');

        try {
            const response = await fetch('/api/ask', {
                method: 'POST',
                headers: {
                    'Content-Type': 'application/json',
                },
                body: JSON.stringify({ question: messageContent })
            });

            if (!response.ok) {
                throw new Error('Network response was not ok');
            }

            const result = await response.json();

            if (result.data && result.data.content && typeof result.data.content === 'object') {
                // Assuming content is an array and contains text or object with 'text' property
                const messageText = result.data.content.map((item: { text: any; }) => item.text || '').join(' ');
                displayMessage(messageText, 'left');
            } else {
                // Default text if content is not structured as expected
                displayMessage('No detailed response available.', 'left');
            }
        } catch (error) {
            console.error('Error:', error);
            displayMessage('Sorry, there was a problem with the server.', 'left');
        }
    }

    function displayMessage(message: string, side: string) {
        const messagesContainer = document.getElementById('messages');
        if (!messagesContainer) return; // Check if messagesContainer is not null

        const messageDiv = document.createElement('div');
        messageDiv.classList.add('text-sm', 'p-2', 'rounded-lg', 'mb-2', 'clear-both');
        
        if (side === 'left') {
            messageDiv.classList.add('bg-gray-100', 'float-left');
        } else {
            messageDiv.classList.add('bg-blue-500', 'text-white', 'float-right');
        }

        messageDiv.textContent = typeof message === 'string' ? message : 'No text available';
        messagesContainer.appendChild(messageDiv);
        messagesContainer.scrollTop = messagesContainer.scrollHeight; // Scroll to the bottom
    }
