I have an assignment to complete a function that makes API requests using a name. This request will return a json object and this object has a 'height' field that the function should return. I tried but my solution odes not seem to work. Below is my code. Can someone point me in the right direction?

async function getHeight(name) {

  let url = "sample url"
  https.get(url, (resp) => {
  let data = '';

    resp.on('data', (chunk) => {
      data  = chunk;
  });

  resp.on('end', () => {
    let result = (JSON.parse(data));
    let result_data = result[data];
    if(result_data == null){
      return -1
    } else{
      let cataJson = (JSON.parse(result_data));
      return cataJson["height"];
    }
  });

  }).on("error", (err) => {
    return -1;
  });
}

   async function getHeight(name) {
     let url = "sample url"
     try {
         let res = await fetch(url);
         return await res.json();
     } catch (error) {
         console.log(error);
    }
}

this code should be some thing like what you need. you make a get request to the url then you parse the given data to json format then the function returns that data.

You can use fetch with promise like this.

async function getHeight(name) {
  return new Promise((resolve, reject)=>{
      let url = "sample URL"
       fetch(url)
         .then(res=>res.json())
         .then(data=>{
            let result = (JSON.parse(data));
            let result_data = result[data];
            if(!result_data)resolve(-1)
            else resolve((JSON.parse(result_data)).height)
         })
         .catch(e=>{reject()})
  })
}

And to call the function

async function main(){
  try{
    var height = await getHeight("John");
    console.log(height)
   }catch(e){
     console.log("Error Fetching height")
   }
}
main()

 const getHeight = async (name) {
     let url = "url"
     try {
         let res = await fetch(url,{
             method: "GET"
          );

          if (res.ok == true) {
         return await res.json();
         } else {
         throw new Error("error")
        }
     } catch (error) {
         console.log(error);
    }
}
