Why does the request pass through cURL, but I get 429 through nodeJS?

Question

Node.js

I am writing a request for a third-party service.
If you run curl -I then the answer is normal and complete.
If I write:

request(url, options.requestOptions, function(err, res, body) {
   console.log(body);
});

That apparently does not reach the callback.
And if I write

axios({
    ...options.requestOptions,
    method: 'get',
    url: url
  }).then((resp) => {
    console.log(resp.data);
    callback('axios done');
  }).catch((err) => {
    console.log(err.response.status);
    console.log(err.response.headers);
    callback('error');
  }).finally(() => { })

Then an error is triggered and I get status 429, they say there are too many requests.
My answer should come in chunks Transfer-Encoding: chunked but normally only comes through curl. Why can this be so?
