picking out objects in json file not working javascript

Question

I'm using the Discord API and I want it to send the longitude and latitude of the ISS using the "where the ISS at" API, but if I try and pick an object out of the JSON it comes back empty.

if (message.content.startsWith(`${prefix} were is the iss`)) {
  const https = require('https');

  https.get('https://api.wheretheiss.at/v1/satellites/25544', (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', () => {

      console.log(JSON.parse(data).explanation);
      const {
        lattitude,
        longitude
      } = data;
      console.log(lattitude)
      console.log(longitude)
      message.channel.send(`ok  ${data}`)
    });

  }).on("error", (err) => {
    console.log("Error: " + err.message);
  })
}

Seems like as of now you are trying to pick out latitude and longitude from the string data. You are parsing it to JSON but not reassigning it, as JSON.parse does not parse in place. You can find more on that here.

Here is what you should be doing-:

const {latitude, longitude} = JSON.parse(data);

is your data a JS object when you destruct?
spell latitude correctly
there is no explanation in a valid response:

{
  "name": "iss",
  "id": 25544,
  "latitude": -48.568896551266,
  "longitude": 153.94349230508,
  "altitude": 436.29840426652,
  "velocity": 27536.388032323,
  "visibility": "eclipsed",
  "footprint": 4589.4699866736,
  "timestamp": 1592575515,
  "daynum": 2459020.0869792,
  "solar_lat": 23.430766332023,
  "solar_lon": 329.0668493775,
  "units": "kilometers"
}

Working code using fetch

fetch('https://api.wheretheiss.at/v1/satellites/25544')
  .then(response => response.json())
  .then(data => {
    const {
      latitude,
      longitude
    } = data;
    console.log(latitude)
    console.log(longitude)
  });
