        lineBotMessageApiPostUrl,
        json,
        {
            headers: {
                'Content-Type': 'application/json',
                Authorization: `Bearer ${env.CHANNEL_ACCESS_TOKEN}`,
            }
        });
    return res.json(response.data);
} catch (error) {
    console.error(error);
    return res.status(500).json({ error: 'Get API Error' });
