Thanks, it was successfully on my code. :)

const express = require('express');
const router = express.Router();
const request = require('request');

router.get('/', async(req, res, next) => {
console.log('el cuerpo del filtro: ', req.body);
const data = {
template: { 'shortid': 'rkg6sD1NY8' },
options: {
preview: true
}
};
const options = {
uri: 'http://localhost:3001/api/report',
method: 'POST',
json: data
}
request(options).pipe(res);
//res.send('recibiendo');
});

module.exports = router;
