Get data from array in nested json using Google Script - json

Question

I need to fix a Google Script I've been working on. Basically, I have a json https://www.instagram.com/nike/?__a=1 that returns basic info about Nike's account on instagram. I have no problem retrieving data from objects such as "biography". But, when I try to retrieve nested objects (arrays) I'm doing something wrong because the results arrive duplicated (see attachment). Can anyone help me figure out what I'm doing wrong?
// the name of the sheet within your document
var sheetName = "Sheet1";
// the name of the Instagram account you want the follower count for
var instagramAccountName = "nike";
function insert() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName(this.sheetName);
var followers = [];
var followers = captionArray(this.instagramAccountName);
for(var i = 0 ; i < 3; i++) {
sheet.appendRow([Utilities.formatDate(new Date(), "GMT", "yyyy-MM-dd"), followers]);
};
}
function captionArray(username) {
var i = 0;
for(var i = 0; i < 3; i++) {
var url = "https://www.instagram.com/" + username + "/?__a=1";
var response = UrlFetchApp.fetch(url).getContentText();
var caption = [];
var caption = JSON.parse(response).graphql.user.edge_owner_to_timeline_media.edges[i].node.edge_media_to_caption.edges[i].node.text;
return caption;
};
}

I think this is causing problems:
You're using the same index (i) for both arrays, but the second have only one element.
You just need to do one request.
This code works for me:
function captionArray(username) {
var captions = [];
var url = "https://www.instagram.com/nike/?__a=1";
var response = UrlFetchApp.fetch(url).getContentText();
var edges = JSON.parse(response).graphql.user.edge_owner_to_timeline_media.edges;
for(var i = 0, limit = edges.length; i < limit; i++) {
captions.push(edges[i].node.edge_media_to_caption.edges[0].node.text);
}
return captions;
}
