'Response from JS request library changes behavior when used with "response.on"

I am new to nodeJS and wanted help to understand the behavior. I am making a simple request to get zip/json/yaml files using

  • Method 1:
return http.request(options).on('response', (response, body) => {
       var body = [];
       //console.log(response)
       resolve(response)
     });
  • Method 2
const req = http.request(options, (res) => {
          if (res.statusCode < 200 || res.statusCode >= 300) {
                return reject(new Error('statusCode=' + res.statusCode));
            }
            var body = [];
          const response = lodash.cloneDeep(res);
          //console.log(res)
            res.on('data', function(chunk) {
                
                body.push(chunk);
            });
            res.on('end', function() {
                try {
                    body = JSON.parse(Buffer.concat(body).toString());
                } catch(e) {
                    reject(e);
                }
                resolve({body, header: res.headers, response});
            });
        });
        req.on('error', (e) => {
          reject(e.message);
        });
        // send the request
       req.end();

And then using response again to send binary zip data. I need both data and response for two different operations. Issue is, when using response.on(, my response object changes is no longer same. Cloning the object has also not solved.

Here are two different responses from above two codes:
