How to get link to composition by using status callbacks twilio - twilio

Question

Here is what I tried but it's not working.
This guy is responsible for creating a composition after the meeting is ended.
app.post('/api/endMeeting', (req, res) => {
const roomSid = req.body.roomSid;
userEmail = req.body.userEmail;
const client = require('twilio')(config.twilio.apiKey, config.twilio.apiSecret, {accountSid: config.twilio.accountSid});
client.video.rooms(roomSid).update({ status: 'completed' });
client.video.compositions.create({
roomSid: roomSid,
audioSources: '*',
videoLayout: {
grid : {
video_sources: ['*']
}
},
statusCallback: `${process.env.REACT_APP_BASE_URL}/api/getMeeting`,
statusCallbackMethod: 'POST',
format: 'mp4'
}).then(() => {
// sendRecordingEmail(composition.sid, userEmail);
res.status(200).send({
message: 'success'
});
}).catch(err => {
res.status(500).send({
message: err.message
});
});
});
And this guy will send the download link of the composition to the participant when it's available.
app.post('/api/getMeeting', (req, res) => {
if (req.query.StatusCallbackEvent === 'composition-available') {
const client = require('twilio')(config.twilio.apiKey, config.twilio.apiSecret, {accountSid: config.twilio.accountSid});
const compositionSid = req.query.CompositionSid;
const uri = "https://video.twilio.com/v1/Compositions/" + compositionSid + "/Media?Ttl=3600";
client.request({
method: "GET",
uri: uri,
}).then((response) => {
const requestUrl = request(response.data.redirect_to);
sendRecordingEmail(requestUrl, userEmail);
res.status(200).send("success");
}).catch((error) => {
res.status(500).send("Error fetching /Media resource " + error);
});
}
});
I can confirm that the composition is created exactly in the Twilio console.
But it seems the status callback guy is not working and I can see the below issue.
It seems I made mistakes in using the status callback.
Please let me know what is the problem and how I can solve this.
Thank you.

Thank you very much for #philnash's help in solving this problem.👍
I solved the above issue and I can get the download link of the composition for now.
The problem was in the status callback function and I should use req.body instead of req.query because of the status callback method. (It's POST on my code.)
Here is the code that is fixed.
app.post('/api/getMeeting', (req, res) => {
if (req.body.StatusCallbackEvent === 'composition-available') {
const client = require('twilio')(config.twilio.apiKey, config.twilio.apiSecret, {accountSid: config.twilio.accountSid});
const compositionSid = req.body.CompositionSid;
const uri = "https://video.twilio.com/v1/Compositions/" + compositionSid + "/Media?Ttl=3600";
client.request({
method: "GET",
uri: uri,
}).then((response) => {
const requestUrl = response.body.redirect_to; // Getting the redirect link that user can download composition
sendRecordingEmail(requestUrl, userEmail); // Send URL via email to the user
res.status(200).send("success");
}).catch((error) => {
res.status(500).send("Error fetching /Media resource " + error);
});
} else {
res.status(204).send('compositioin is not available');
}
});
