Axios post request and other node modules that send api requests work locally and on github server, but not on Vercel

Summary

I have tried to send a post request from my next.js app and the request works both locally and when deployed on github server when running a github action, but that same request does not work when deployed to vercel. When I say it doesn't work I don't get a 401 or a 404 or any status errors. It simply appears to not even execute the request - I try to print logs using console.log, but nothing is being logged within the request.
There are no errors nor warnings when deploying or running the app.

Here is a snippet of code I've tried (works locally, doesn't work on vercel)

`
const _payload = {
event: {
message: { ResponseJson }
},
sourcetype: "_json"
};

const agent = new https.Agent({
rejectUnauthorized: false
});
const config: AxiosRequestConfig = {
headers: _headers,
httpsAgent: agent,
timeout: 10000
};
// Send the POST request
async function sendPostRequest() {
try {
const response = await axios.post('URL', _payload, config);
// Process the response (response data type is 'any')
console.log('Response:', response.data);
} catch (error) {
if (axios.isAxiosError(error)) {
console.error('Axios error:', error);
} else {
console.error('Unexpected error:', error);
}
}
}
console.log('trying post request')
sendPostRequest();
// Axios done
console.log('done with post request')`

Hey ! Same problem here, did you find a solution ?

Yea what I did was create a separate function that returned a promise. And then I awaited that function.
The way vercel handles serverless functions caused it to skip the callback, so explicitly wrapping the request in something like:
return new Promise((resolve, reject) => {
worked for me
