I want to send a request to another API to get list of currency prices.

 https.get(this.baseUrl, (response) => {
                response.on('data', async (chunk) => {
                model = JSON.parse(JSON.stringify(chunk.toString('utf-8')));
      })
   });

response :

    {
      "success":true,
      "timestamp":1641994743,
      "base":"EUR",
      "date":"2022-01-12",
      "rates":{
        "AED":4.184454,
        "AFN":120.094117,
        "ALL":122.214122,
        "AMD":548.537072,
        "ANG":2.052899,
        "AOA":609.048742
         }
    }

I got array buffer and I use this command to convert that to a string model :

chunk.toString('utf-8')

when I use JSON.parse(chunk.toString('utf-8')) it show me this error :

UnhandledPromiseRejectionWarning: SyntaxError: Unexpected end of JSON input

and when I want to use this code :

model = JSON.parse(JSON.stringify(chunk.toString('utf-8')));

I can not access to model property . for example I an not access to model.success or model['success'] it show me undefined.

now whats the problem ? how can I solve this problem ?
