Node return page

I have the following code block

 server.get('/energy', (req, res, next) => {
{
  const getScript = (url) => {
    return new Promise((resolve, reject) => {
      const http = require('http'),
        https = require('https')

      let client = http

      if (url.toString().indexOf('https') === 0) {
        client = https
      }

      client.get(url, (resp) => {
        let data = ''

        // A chunk of data has been recieved.
        resp.on('data', (chunk) => {
          data += chunk
        })

        // The whole response has been received. Print out the result.
        resp.on('end', () => {
          resolve(data)
        })
      }).on('error', (err) => {
        reject(err)
      })
    })
  };

  (async (url) => {
    console.log('Async ' + await getScript(url))
  })('http://localhost:81/energia/monitoramento/central.php?ip=147.1.3.3')
  const ret = async (url) => {
    const dados = await getScript(url)
    console.log(url)
    console.log('retorno: ' + dados)
    return dados
  }// ('http://minhaurl.com')
  console.log('Dados de retorno: ' + ret('http://minhaurl.com'))
  res.send(ret('http://minhaurl.com'))
  next()
}

})

Where I would like to return the value that a certain page brings.

For example, the

 (async (url) => {
            console.log(await getScript(url))
          })('http://minhaurl.com')

At the console it looks like this:

  

Async   [129.66,30.27,3924.31,2721.89,0.69,0.00,0.00,0.00,2826.94,0.00,129.56,31.45,4075.07, -2453.22, -0.60,0.00,0.00,0.00,3253.91,0.00,128.81,29.19,3760.38, - 514.79, -0.14, -1.00, -1.00, -1.00.3724.98,59.76,30.60,35.10]

Nestre excerpt

const ret = async (url) => {
        const dados = await getScript(url)
        console.log(url)
        console.log('retorno: ' + dados)
        return dados
      }

also looks like this: etorno:

  

[129.59,30.44,3944.05,2768.30,0.70,0.00,0.00,0.00,2809.28,0.00,129.60,31.92,4137.48, -2462.13, -0.60,0.00,0.00,0.00,3325.15,0.00,128.81,29.33, 3778.27, -558.25, -0.15, -1.00, -1.00, -1.00.3736.80,59.86,30.60,35.00]

I'm trying to show this data on the page with this

console.log('Dados de retorno: ' + ret('http://localhost:81/energia/monitoramento/central.php?ip=147.1.3.3'))
      res.send(ret('http://localhost:81/energia/monitoramento/central.php?ip=147.1.3.3'))
      next()

But the return says like this:

  

Return data: [object Promise]

And the page appears only like this: {}

How do I show the same data that appears in the console on the page?
