Javascript – I want to auto update the Primary handler fails webhook Url using twilio functions, can someone guide me?

i used the following function and trying to run HTTP request from postman using curl but didn’t work

exports.handler = function(context, event, callback) {
    const client = context.getTwilioClient();
    const new_fallback_url = 'http://your_twilio_function_url.com/webhooks/twilio_voice_fallback'; // Replace with your actual Twilio Function URL

    // Fetch all phone numbers and update them
    client.incomingPhoneNumbers.list()
        .then(phoneNumbers => {
            const updates = phoneNumbers.map(number => {
                return client.incomingPhoneNumbers(number.sid)
                    .update({ voiceFallbackUrl: new_fallback_url });
            });
            return Promise.all(updates);
        })
        .then(results => {
            callback(null, `Fallback URL updated for ${results.length} numbers`);
        })
        .catch(error => {
            callback(error);
        });
};

I want after running the code all my twilio number will automatically updated
