Website visitor counter showing up as "[object Object]"

I am trying to setup a view counter for the AWS #CloudResumeChallenge. I am following the instructions on these two youtube videos:

• "Cloud Resume Challenge Sprint (Sept, 2022) – Week 2" -> https://youtu.be/vOZ-sMgAUFk
• "Setup CORS (with AWS Lambda & API Gateway) – The Cloud Resume Challenge Series (Part 10)" -> https://youtu.be/MsFYWnjP39M

I am also using both of these gentlemen’s GitHub repos as references:

• CumulusCycles -> https://github.com/CumulusCycles/CloudResumeChallenge/tree/main/Week_4
• openupthecloud -> https://github.com/openupthecloud/cloud-resume-challenge/tree/setup-cors-configs

I have followed the video’s instructions, step-by-step; however, when I load my cloud resume at https://justinhenson.cloud/, the visitor counter is showing "[object Object]" and upon inspecting the element, the original line in my index.html file changes from this:

<div id="visitors" class="visitors"> You are visitor number<span id="visits"></span><span id="loader" class="loader"></span></div>

To this:

<div id="visitors" class="visitors"> You are visitor number<span id="visits">[object Object]</span><span id="loader" class="loader" style="display: none;"></span></div><span id="visits">[object Object]</span><span id="loader" class="loader" style="display: none;"></span></div>

Also, as you can see in my scripts.js file below, I have pointed the pathway to the AWS API Gateway to trigger the lambda handler:

"use strict";

$(document).ready(() => {
    $.post('https://pl8h7bxm3j.execute-api.us-east-1.amazonaws.com/Prod/visit/')
    .done(visitor_counter => {
        $('#loader').hide();
        $('#visits').text(visitor_counter);
    })
    .fail(e => {
        console.log('Error');
        console.log(e);
    });
});

I have tested my API Gateway with the Postman app and it returns the count without error:

I followed both of the instructions in the videos by enabling the CORS policy in my lambda handler in the "app.py" file to be wide open to reduce complexity:

import json
import boto3

dynamodb = boto3.resource('dynamodb', region_name='us-east-1')

table = dynamodb.Table('resume-website-app-tbl')

def lambda_handler(event, context):
    response = table.get_item(
        Key = {
            'ID':'visits'
        }
    )
    
    visit_count = response['Item']['counter'] 
    visit_count = str(int(visit_count) + 1)
    
    response = table.put_item(
        Item = {
            'ID':'visits',
            'counter': visit_count
        }
    )

    return {
        'statusCode': 200,
        'headers': {
            'Access-Control-Allow-Headers': '*',
            'Access-Control-Allow-Origin': '*',
            'Access-Control-Allow-Methods': '*'
        },
        'body': json.dumps({'visit_count': visit_count})
    }

Below is my template.yaml file that I built with SAM that contains the configuration for my CloudFront Distribution under "MyDistribution" and the configuration for MyLambdaFunction:

I sincerely appreciate any help anyone can offer in shedding some light on this issue. Thanks.

>Solution :

You are trying to put all HTTP response object to html, so you get [object Object]

$(document).ready(() => {
    $.post('https://pl8h7bxm3j.execute-api.us-east-1.amazonaws.com/Prod/visit/')
    .done(res => {
        $('#loader').hide();
        $('#visits').text(res.visit_count);
    })
    .fail(e => {
        console.log('Error');
        console.log(e);
    });
});
