    Thank you for this project!! It is working Very Insightful
    Now many people are getting error in different stages I will explain how i did troubleshooting:
    1. Everyone while you are creating dynamodb table and partition key please keep name as shown in video otherwise you will have to make changes in scripts applicable only if you are using code from this video.
    2. I have created role for lambda function and given them full access to dynamodb and api gateway
    3. In get function script do change the region
    4. While testing event in lambda for insert function please check format of your json otherwise you will get errors
    5. After creating api gateway do add endpoint in js file and do click on deploy.
    6. After uploading my files in s3 bucket and attaching policy i was able to open my website but i was not able perform any action as i was getting popup about error. After checking in inspect > console i got cors related error. You have to attach cors policy for you s3 bucket
    policy :
    [
    {
    "AllowedHeaders": [
    "*"
    ],
    "AllowedMethods": [
    "GET",
    "POST",
    "PUT",
    "DELETE",
    "HEAD"
    ],
    "AllowedOrigins": [
    "*"
    ],
    "ExposeHeaders": [
    "ETag"
    ],
    "MaxAgeSeconds": 3000
    }
    ]
    As for cloudfront i have not gotten any error. That's it!

    Finnally it works. Thank you for this project.
    If your getting error while invoking from website then you must enable cors for your API and then click on deploy api option. In my case i just enable cors but not deployed the api due to which it was not working. When you make any changes, you must deploy it.
    Even if you are getting error then enable cloudwatch logs for API. In my case it helps a lot.

    FYI to anyone having issues at the test event around 8:00 , he just completely glosses over the fact he had a ready-made role for that function that had the correct permissions. To fix, search for the service IAM at the top bar, go to roles on the left, create role, "use case" is Lambda and next, checkmark the permission "DynamoDBFullAccess", then next and name it something lambda+dynamo related and create role. then go back and follow his video but when it gets to the role field choose the one you made.

    Thank you. Good video. One note, if you add CloudFront you need to also add invalidation to your lambda every time you make a change because the cache will keep everything the same so you cant see updated table in real time. Also, how did you define the lambda role?

    The CSV in case I'm getting it via this URL, is updated daily, it contains hedge funds in Brazil, therefore it's updated daily with info such as the fund's name, value, and so on.
