Missing a parenthesis at ECS node.js logging

[liu-xiao-guo]

At the link https://www.elastic.co/guide/en/ecs-logging/nodejs/current/pino.html#pino-ref, there is a missing "(" in the code:

The correct code should be:

const http = require('http');
const { ecsFormat } = require('@elastic/ecs-pino-format');
const pino = require('pino');

const log = pino(ecsFormat({ convertReqRes: true })); 

const server = http.createServer(function handler (req, res) {
  res.setHeader('Foo', 'Bar');
  res.end('ok');
  log.info({ req, res }, 'handled request'); 
});

server.listen(3000, () => {
  log.info('listening at http://localhost:3000');
})
