JSON Object Undefined (Nodejs)

I'm trying to access a JSON object but I'm getting errors while accessing the object. Could you please go through the code and let me know the mistake I'm making.

I'm writing 2 different cases to give a better understanding about my problem

Here's the JSON data:

JSON DATA

Case 1:

If I just try to access the company_base object, I'm getting the Undefined value 

if(!error && response.statusCode == 200){
  console.log("Insurance name is.....");
    var parsedData = JSON.parse(body);
    console.log(parsedData["company_base"]);
  }

Result: Insurance name is..... undefined

CASE 2:

I'm attaching 2 images. One contains the JSON text and the other contains the error I'm getting while trying to access the JSON object.

//This is the Code I'm using to access the object

   if(!error && response.statusCode == 200){
    console.log("Insurance name is.....");
    var parsedData = JSON.parse(body);
    console.log(parsedData["company_base"][""business_type"]);
   }

Insurance name is..... C:\Users\Ebbie\Desktop\Misc\mean\udemy\the web developer bootcamp\IntroToApis\CSG\app.js:37 console.log(parsedData["company_base"]["business_type"]); ^

You are getting undefined because parsedData is an array of one element. Notice [ at the beginning of the json data. Instead of using parsedData["company_base"] to get value, iterate over it.

'use strict';

let _ = require('lodash');

if (!error && response.statusCode == 200) {
  let insuranceCompanies = JSON.parse(body);
  _.each(insuranceCompanies, (company) => {
    let companyBase = company.company_base;
    console.log('Insurance name is.....', companyBase.business_type);
  });
}

Since company_base and business_type are static keys, I am using dotted notation to its access value.

It's returning an array of objects. parsedData["company_base"] is trying to access the company_base key on the array.

You would want something like this:

parsedData[0]["company_base"]

And..

parsedData[0]["company_base"][""business_type"]
