When your error message says Task timed out after XX.00 seconds, it means that AWS intentionally stopped the task once it hit a run-time of XX seconds.
This error message means that you have exceeded the memory allocation of your Lambda function.
The message "Process exited before completing request" means that the function exited before calling context.done (or context.succeed, etc.).
This error occurs when the Lambda function is not able to initialise and the execution halts before reaching the handler function.
An exception is any error condition or unexpected behavior that is encountered by an executing program.
An exception is any error condition or unexpected behavior that is encountered by an executing program. Exceptions can be thrown because of a fault in your code or in code that you call.
Why do I see this? One of your functions has been nearing the limit of 90% during the last 30 minutes. What does this mean? When you deploy a Lambda function, you need to configure a timeout. After the configured time, the Lambda service will force your function to stop. For your function, this will […]
Why do I see this? More than 5% of one of your function’s invocations are failing. What does this mean? You have some kind of bug in your code that crashes the Lambda runtime. If the error percentage rises but doesn’t go up to 100%, this can be a data-related bug. This event can be […]
Why do I see this? One of your functions uses a dangerously high amount of memory and could hit the limit soon. What does this mean? When you deploy a Lambda function, you need to configure a memory limit for it. To keep costs low, you usually try to find a memory configuration that doesn’t […]
Why do I see this? One of your functions is using an outdated runtime and could be upgraded to a new version. What does this mean? Lambda offers different officially AWS’ supported language runtimes which are updated regularly. Runtime updates can bring many benefits like improved security or performance. AWS also doesn’t support every runtime […]
Why do I see this? One of your functions didn’t have any invocations for a long time. What does this mean? You have deployed a function to AWS, but it’s never invoked. This can be a bug, and the function should actually be called and do important work, or it can simply be that the […]
Why do I see this? One of your functions doesn’t have any tags associated with it. What does this mean? Every resource in AWS can be tagged. Tags are metadata for your resources and help to understand them better. If a Lambda function isn’t tagged, it becomes harder to reason about it in the future. […]
