Can the Couchbase NodeJS SDK return a JSON document as a raw JSON string, without parsing it first?

This seems to work

const couchbase = require('couchbase');
const { Readable, PassThrough } = require("stream");

async function main() {

  const cluster = await couchbase.connect('couchbase://localhost', {
    username: 'Administrator',
    password: 'password',
  });

  const readableStream = new Readable({
    read() {},
  });

  const query = "SELECT RAW ENCODE_JSON(a)   FROM `travel-sample` a limit 2";

  const queryStream = cluster.query(query);
  queryStream.on('row', (row) => {
      console.log('row: ',row, typeof(row));  // to show that the row is a string
      readableStream.push(row + '\r\n');  // adding \r\n shouldn't be necessary
    });
  queryStream.on('end', () => {
      readableStream.push(null);
    });

   //setStreamHeaders(res);
   //readableStream.pipe(res.raw);

    readableStream.pipe(process.stdout)
}

main().catch(e => console.log(e));  // this catch doesn't seem to work as I hoped.

row:  {"callsign":"MILE-AIR","country":"United States","iata":"Q5","icao":"MLA","id":10,"name":"40-Mile Air","type":"airline"} string
{"callsign":"MILE-AIR","country":"United States","iata":"Q5","icao":"MLA","id":10,"name":"40-Mile Air","type":"airline"}
row:  {"callsign":"TXW","country":"United States","iata":"TQ","icao":"TXW","id":10123,"name":"Texas Wings","type":"airline"} string
{"callsign":"TXW","country":"United States","iata":"TQ","icao":"TXW","id":10123,"name":"Texas Wings","type":"airline"}

Later I found there is somewhat of an answer here that also points to ENCODE_JSON. How convert json object to string?
