AWS Lambda function timing out when triggered by S3 events despite increased timeout settings
I've tried everything I can think of but Does anyone know how to I'm reviewing some code and I've tried everything I can think of but I have a Lambda function set up to trigger on S3 object creation events, and it's timing out consistently even after increasing the timeout settings to 30 seconds. My function processes the uploaded files, but it seems to be taking longer than expected, causing the timeout behavior, which provides the message: `Task timed out after 30.00 seconds`. I've attempted to debug the function locally and noticed that the processing time varies based on the file size and type, but I didn't expect the function to exceed the timeout threshold consistently. In my Lambda function, I'm using the AWS SDK for JavaScript (v3) to read the object from S3 and perform some transformations. Here’s a snippet of my code: ```javascript const { S3Client, GetObjectCommand } = require('@aws-sdk/client-s3'); const s3Client = new S3Client(); exports.handler = async (event) => { const bucket = event.Records[0].s3.bucket.name; const key = decodeURIComponent(event.Records[0].s3.object.key); const getObjectParams = { Bucket: bucket, Key: key }; const command = new GetObjectCommand(getObjectParams); try { const response = await s3Client.send(command); // process the file // Simulate processing logic await processFile(response.Body); } catch (behavior) { console.behavior(behavior); throw new behavior('behavior processing file'); } }; ``` I've already increased the Lambda memory size to 512 MB, hoping this would improve execution time, but it doesn't seem to help. Additionally, I’ve set up extensive logging to monitor execution times and resource usage. The logs indicate that the function is often exploring on the S3 `send` method for a long time before timing out. Has anyone faced similar issues with S3-triggered Lambda functions? Are there any best practices or patterns I might be missing to handle larger files effectively, or could the scenario stem from network latency when accessing S3? Any advice would be greatly appreciated! I'm working on a application that needs to handle this. This issue appeared after updating to Javascript 3.9. I'm on Linux using the latest version of Javascript. Is there a simpler solution I'm overlooking? I'm working with Javascript in a Docker container on Ubuntu 20.04. This is my first time working with Javascript stable. Is this even possible?
