How to correctly set recursion for map in nodejs?

Question

JavaScript

There is this code:

longPoll(callback) {
    let longPollMap = new Map();
  this.arg = 0;
    longPollMap.set('getLongPoll', () => {
      this.callMethod('messages.getLongPollServer', {}, (body) => {
        this.tempPoll     = JSON.parse(body)['response'];
        longPollMap.get('callLongPoll')();
      });
    });
    
    longPollMap.set('callLongPoll', () => {
    if(this.cap==false) {
    request({
        url: 'https://'+this.tempPoll['server'],
        qs: { 
          act:         'a_check',
          key:          this.tempPoll['key'].substr(0, (this.tempPoll['key'].length - 10)),
          ts:           this.tempPoll['ts'],
          wait:         25,
          mode:          2
        }
      }, (error, response, body) => {
    try { 
          body = JSON.parse(body);
          if('failed' in body)
            longPollMap.get('getLongPoll')();
          else {
     this.tempPoll['ts'] = body['ts'];
     }
           callback(body);
     longPollMap.get('callLongPoll')();
        } catch(e) {
          console.log('LONGPOLL: '+e);
          longPollMap.get('getLongPoll')();
        }
      });
    } else longPollMap.get('callLongPoll')();
    
    });
  
    longPollMap.get('getLongPoll')();
  }

As soon as cap becomes true, recursion should occur until it becomes false (another function performs). But the trouble is that the RangeError: Maximum call stack size exceeded error is returned and the application is restarted. How to do recursion?
