node.js - Error parsing array containing buffers from two sequential Youtube API requests -

i trying playlists on youtube channel. chunks parses no problem when request either 1st https.get (first 50 playlist titles) or 2nd(nested) https.get(next 50 playlist titles)

however, if both requests , push 100 titles (5 buffers each request) chunks, parsing problem unexpected token { in json @ position 6508.

how can parse chunks contains information of 100 titles both https.get instead of either first 50 or next 50 only?

full parsable (first 50 playlist) code below:

var util = require('util'); var https = require('https'); var fs = require('fs'); var count = 1;  https.get('https://www.googleapis.com/youtube/v3/playlists?maxresults=50&fields=items(snippet/title,contentdetails)&part=snippet%2ccontentdetails&channelid=ucjbpgzawdh1njbqv-d5hqkw&key=aizasydgkgcw_vv8onuonht-dgeww3uryomsfzu',function(response){     console.log("status code is: "+response.statuscode);     var chunks = [];     //var chunks = new buffer(0);      response.on('data', (json) => {chunks.push(json);});    // response.on('data', (json) => {chunks = buffer.concat([chunks ,json]);   })    //if using chunks = new buffer(0)     response.on('end',() => {      https.get('https://www.googleapis.com/youtube/v3/playlists?pagetoken=cdiqaa&maxresults=50&fields=items(snippet/title,contentdetails)&part=snippet%2ccontentdetails&channelid=ucjbpgzawdh1njbqv-d5hqkw&key=aizasydgkgcw_vv8onuonht-dgeww3uryomsfzu',function(response){    // response.on('data', (json) => {chunks.push(json);});     response.on('data', (json) => {                  });   // response.on('data', (json) => {chunks = buffer.concat([chunks ,json]);   })     //if using chunks = new buffer(0)          response.on('end',() => {                var parsedjson = json.parse(buffer.concat(chunks).tostring());               //  var parsedjson = json.parse(chunks.tostring());                     parsedjson.items.foreach(function(item){                      console.log(count+". "+item.snippet.title + "   " + '\x1b[33m%s\x1b[0m:', item.contentdetails.itemcount + " videos");                      fs.appendfilesync("message.txt",count+". "+item.snippet.title + "   " + item.contentdetails.itemcount + " videos\n", {flags: 'a'});                      count++;  //labeling list                     });                   })             })                             }); }); 

changing response.on('data', (json) => { }); to

response.on('data', (json) => {chunks.push(json);});

to add next 50 playlist chunks generate parsing error of unexpected token.

i have tried using var chunks = new buffer(0) response.on('data', (json) => {chunks = buffer.concat([chunks ,json]); }) , var parsedjson = json.parse(chunks.tostring()); generates same unexpected token error, solved if 1 of 2 requests pushed chunks.

printing chunks after executing both requests shows 100 results (10 buffers) 2 requests formatted, can't figure out why chunks has token errors when parse it.
