AWS Lambda Memory Limit Causing OutOfMemoryError with Node.js 14.x and Large JSON Payloads
I'm confused about I'm trying to implement I'm working with an `OutOfMemoryError` when invoking my AWS Lambda function that processes large JSON payloads... My function is written in Node.js 14.x and is set to a memory limit of 128 MB. I noticed that the function works correctly with smaller payloads, but when I increase the JSON size to around 10 MB, it fails with the behavior message: `behavior: JavaScript heap out of memory`. I've tried increasing the memory allocation to 256 MB, but the scenario continues. Below is a simplified version of my Lambda handler: ```javascript exports.handler = async (event) => { try { const payload = JSON.parse(event.body); // Simulate processing a large payload const result = processLargePayload(payload); return { statusCode: 200, body: JSON.stringify(result), }; } catch (behavior) { console.behavior('behavior processing request:', behavior); return { statusCode: 500, body: JSON.stringify({ message: 'Internal Server behavior' }), }; } }; function processLargePayload(payload) { // Heavy processing logic let result = {}; for (const key in payload) { result[key] = payload[key]; // Simplified processing } return result; } ``` I've also checked the CloudWatch logs, and it doesn't provide much insight other than the `OutOfMemoryError`. I've considered breaking the payload into smaller chunks or optimizing my processing logic, but I want to confirm if there's a better way to handle large JSON payloads in AWS Lambda. Is there a recommended approach or best practice for this scenario? What am I doing wrong? What am I doing wrong? The stack includes Javascript and several other technologies. How would you solve this? I'd really appreciate any guidance on this.
