Main question => How to post/write the array on a right way with NodeJs http request? (or other way)

The PHP API request array as input. Based on the example it is also need to be converted by http_build_query. The http_build_query PHP function create a following sting: “order_ids%5B0%5D=123&order_ids%5B1%5D=456&order_ids%5B2%5D=789”

$curl_parameters['order_ids'] = array(123,456,789);

$curl_options = array(
    ...
    CURLOPT_POSTFIELDS => http_build_query($curl_parameters),
    ...
  );

I try to do the same in NodeJs but some reason I can not send the array on a right way therefore I always got the following error message:
"

//error=> implode(): Invalid arguments passed.{"result":"success","event":"getawb","msg":[]}

"

What I have tried:

const order_ids = { "order_ids": [123,456,789] }  
const order = httpBuildQuery(order_ids)   //This line create a same format like in PHP script. It is an NPM package.

const options = {
    mehod: 'POST',                                             
    auth: username + ":" + password,
  };
const req = http.request(url, options, (res) => {                   
    
    res.on('data', (d) => {                                 
        process.stdout.write(d);
      });                                           

  req.write(order);  
  req.end();
};
