How can I get d value from process.stdout.write(d)-CodePudding

I have that 'd' where is stored the access token, how can I get this value from him, if I'm using console.log(d) I'm getting this:

 <Buffer 7b 22 61 63 63 65 73 73 5f 74 6f 6b 65 6e 22 3a 22 65 61 38 30 66 32 30 35 38 38 32 37 34 64 37 32 62 61 64 66 30 36 31 37 64 36 37 62 36 65 34 38 22 ... 362 more bytes>

I tried with toString(),str='',str =d but I can't get it

const auth=()=>{
    const data=querystring.stringify({
        grant_type: 'client_credentials',
        client_id: 'x',
        client_secret: 'x',
    })
    var options = {
      port:443,
      host: 'rest.sandbox.eu.zuora.com',
      path:'/oauth/token',
      headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'Content-Length': data.length
       },
       method: 'POST',
    };
    const req=https.request(options,(res)=>{
    
        res.on('data', (d) => {
         process.stdout.write(d)
         }).on('end',()=>{
             console.log("Yay");
         });
    })
    req.write(data)
    req.end()
    }
    auth()

Try something like this (not tested)

const auth=()=>{
    const data=querystring.stringify({
        grant_type: 'client_credentials',
        client_id: 'x',
        client_secret: 'x',
    })
    var options = {
      port:443,
      host: 'rest.sandbox.eu.zuora.com',
      path:'/oauth/token',
      headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'Content-Length': data.length
       },
       method: 'POST',
    };
    const req=https.request(options,(res)=>{
    
        let body = []
        res.on('data', (d) => {
            body.push(d)
        }).on('end',()=>{
            try {
                console.log(JSON.parse(Buffer.concat(body).toString()));
            } catch(e) {
                console.log('some error')
            }
         });
    })
    req.write(data)
    req.end()
    }
    auth()

I'm not sure how you are using toString, but if I invoke toString(), as

theString = d.toString()

it works for me.
