I am trying to ask question a specific assistant ( trained before ) but getting this error.

#code
`app.post(‘/ask’, async (req, res) => {
try {
const { question } = req.body;
const response = await openaiClient.assistants.complete(“asst_87GJOLpKrQGen2MrjIIiLO5U”, {
messages: [{ role: ‘user’, content: question }],
});
const assistantReply = response.data[0].content;

    res.json({ reply: assistantReply });
} catch (error) {
    console.error('Error asking question:', error);
    res.status(500).json({ error: 'Failed to ask question' });
}

});`

Here is the issue iam facing
