AWS Lambda Error handling | Lambda Error Handling Best Practices | AWS Serverless Error Handling

Error Handling with AWS Lambda:
In this video, I will explain how you can handle errors/exceptions in AWS Lambda. Considering the use cases and scale at which AWS Lambda is used, it is very important to implement correct error handling for better monitoring and tracing.

hey - you mentioned a link (in the top right corner_ to how to read the cloudwatch logs from athena - but actually no link is there. I wonder if you could share it in the comments. Thanks for this brilliant video.

I need your help i am new to aws. I have small project deployed in aws lambda(java). When I am sending three requests concurrently only one request receives response successfully other two gets 503 service unavailable status code. As per aws documentation max 1000 parallel instances are created if existing lambda function is busy but in my case it looks like its not happening. I dont see any logs related to 503 in watch dog and those 503 failed requests are not even reaching to my function. I dont know how can i check how many number of instances deployed by aws at any given point in time. How I can troubleshoot this?

[@AjayWadhara]

Are you invoking Lambda synchronously or asynchronously ?
Did you check Throttling metric in monitoring?

[@manig1124]

@@AjayWadhara Thanks for reply. I am not sure whether its sync or async but I am using spring cloud handler.
"org.springframework.cloud.function.adapter.aws.FunctionInvoker::handleRequest". And behind I have individual beans which implements Function and Supplier interfaces.

[@kiritik1163]

Check provisioned concurrency limits

I am using serverless spring for aws lambda when i throw any custom exception exception handler us not getting invoked , here my use case doesn't use spi gateway

[@AjayWadhara]

If the code is working on your local, that should work as well in Lambda runtime.
I don’t think there is any special settings to handle Custom Exceptions

[@yashtrivedi6130]

@@AjayWadhara nope the controller advice won't be called when you throw the exception i have tried everything 😞
