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!
@@NishantKumar-bq9lr Go to IAM service - go to role - create new role - select lambda as service - then give permission for api gateway and Dynamodb - then create role
even after doing it get errors then go to api gateway then api then select resources , in a table called resource details there will be an option enable cors , enable it and everything works fine thank you
This project was so well-explained and on-point, I understood every service easily with your help. So glad I decided to watch this video and there was no minute of dissatisfaction. Please keep growing and sharing such valuable projects on cloud !!
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.
@@zakariaShaik-g4x no brother instead I watched another video for building a serverless application which is explained very clearly I could share you the link if you want
A small question, i will not be charged by AWS if i just keep the configurations running in my AWS account right? or do i need to disable some things after use to avoid charges?
during 3.18 time duration can you just check what you are saying "what i heard is by save student data " it will cal get lambda function and "for view it will call post lambda function"??
Thanks for the clear instructions. My html file with the js. does not work . i can open the API endpoint file and see all the json code. but the code keeps telling me "Error retrieving student data" , when i replace the html file with a json to table script i also can't extract the json somehow. Thanks in advance
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?
Can you make a video on project like Serverless Ecommerce Website , full video from the scratch to the end. Please use ReactJS as frontend and nodeJS in lambda function for backend if possible. Although thank you for this video. I look forward for the video on ServerLess Website . Thank you once again.
Thanks. Step 3 to trigger it from the website is not working. No errors. It just doesnt do anything. The test is working from Lambda and from the API gateway. Any suggestions are welcome.
As a DevOps engineer some times you have to write a lambda function but api scripts and application development are developers part of work. Thanks for watching ❤️
With API invoke URL its working but its not working from website. I gave invoke URL in scripts.js file. Ansar, please if there is any error in scripts.js file.
Troubleshoot by placing “url“ in both GET and POST requests in scripts.js rather then using global variable (“API_ENDPOINT”) , try it once! Thanks for watching ❤️
@@DevOpsMaster-un3mseverything is perfect but still it is not adding on dynamodb or view all the data on website. I can add via that test lambda but not from frontend

Hi there! First of all, thank you so much for the video, it helped me a lot. You're the best mate. I wanted to ask you if I had a CSV that has columns such as 'Company name' and 'id' and I wanted to create a search bar that the user would search for any of these two columns and it would get a match or approximate match, is that possible? 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. I tried reaching out to you via the link you left in the comment below, but I couldn't find your LinkedIn. Thanks again, mate.
@@techkunbyamogh No , for free tier aws account you won’t get charged for this project . Why because Amazon will charged based on number of requests or events done to lambda function but for free tier it will be free because you are not going exceed the limit. By the way thanks for watching 😊
