the return value of "org.json.simple.JSONObject.get(Object)" is null even though HTTP request is successful?

Question

So I'm using the Rapid API alpha vantage API to retrieve some stock data. Wrote this code 2 months ago and it successfully printed out the stock price, but when I ran it again today it through this error:

java.lang.NullPointerException: Cannot invoke "java.lang.Double.doubleValue()" because the return value of "org.json.simple.JSONObject.get(Object)" is null

I tried the testing the endpoint on RapidAPI's API playground, which worked. Then I tried calling the json without requesting a specific address and the json was retrieved successfully (Pic of what the json response looks like) It just seems that issues crop up when I call this:

double price = (Double) jsonObject.get("05. price");  

Here is my code. I censored my API key and stuff:

import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;
import org.json.JSONArray;
import org.json.simple.JSONValue;
import org.json.simple.JSONObject;

 public static void main(String[] args) {
        try{
            Helper.requestPrice();
        } catch(Exception e){
            e.printStackTrace();
        }
    }

public static void requestPrice() throws Exception{
        OkHttpClient client = new OkHttpClient();
        String ticker = "msft";

        Request request = new Request.Builder()
    .url("https://alpha-vantage.p.rapidapi.com/query?function=GLOBAL_QUOTE&symbol="+ticker+"&datatype=json")
    .get()
    .addHeader("x-rapidapi-host", "alpha-vantage.p.rapidapi.com")
    .addHeader("x-rapidapi-key", "xxxxxxx")
    .build();

        Response response = client.newCall(request).execute();
        
        String myData = response.body().string();//works
        
        Object obj = JSONValue.parse(myData);  //works
        JSONObject jsonObject = (JSONObject) obj;  //works
        double price = (Double) jsonObject.get("05. price");  
        System.out.println(price);
    }

Thank you!
