How do I get specific value from JSON string in Google Script? - api

Question

I'm trying to extract a specific value from this json file:
An example value I'm looking for is exDividendDate, fmt : 2020-09-24.
The code I've written to extract the value doesn't doesn't extract this or any other value and I'm not sure why. Any help would be greatly appreciated.
The error I get in the Google Apps Script is:
TypeError: Cannot read property 'earningsDate' of undefined (line 44,
file "Stock Database"
function callAPI(symbol) {
// Call the API
var url = 'https://query2.finance.yahoo.com/v10/finance/quoteSummary/'
var modules = "?modules=calendarEvents"
var response = UrlFetchApp.fetch(url + symbol + modules);
// Parse the JSON reply
var json = response.getContentText();
var data = JSON.parse(json);
console.log(data)
return JSON.parse(json)
}
function displayFinancials() {
// Load sheets
var dataSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Results");
var modelSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Financial Ratios Model");
// Get model input data
var company = "Apple"
var symbol = "AAPL"
// call the API
var api = callAPI(symbol);
var results = api[0];
// Output the API result
var output = [company, symbol, results.exDividendDate.fmt]
console.log(output);
dataSheet.appendRow(output)
}

Answer 1

When I saw the JSON data, it seems that exDividendDate is callAPI(symbol).quoteSummary.result[0].calendarEvents. So how about the following modification?
From:
var results = api[0];
To:
var results = api.quoteSummary.result[0].calendarEvents;
