What is causing this TypeError in my Google Apps Script?

Question

I'm trying to call data from Coin Market Cap to a Google sheet via Apps Script. I don't understand the TypeError I'm doing here.

Here is the code:

function getCryptoPrice() {
  var sh1=SpreadsheetApp.getActiveSpreadsheet().getSheetByName("EPS data CMC");
  
  var url="https://pro-api.coinmarketcap.com/v2/cryptocurrency/quotes/latest?symbol=BTC"
  var requestOptions = {
  method: 'GET',
  uri: 'https://pro-api.coinmarketcap.com/v2/cryptocurrency/quotes/latest',
  qs: {
    start: 1,
    limit: 5000,
    convert: 'USD'
  },
  headers: {
    'X-CMC_PRO_API_KEY': '***********hidden*************'
  },
  json: true,
  gzip: true
};
  
  var httpRequest= UrlFetchApp.fetch(url, requestOptions);
  var getContext= httpRequest.getContentText();
  
  var parseData=JSON.parse(getContext);
  sh1.getRange(1, 2).setValue(parseData.data.BTC.quote.USD.price)
}

And the error:

TypeError: Cannot read property 'USD' of undefined
getCryptoPrice  @ Code.gs:24

Answer 1

You're getting that error because parseData.data.BTC is returning an array.

Try changing this to:-

sh1.getRange(1, 2).setValue(parseData.data.BTC.quote.USD.price)

this

sh1.getRange(1, 2).setValue(parseData.data.BTC[0].quote.USD.price)
