AWS Lambda Timeout scenarios when Invoking External API Integration
I'm relatively new to this, so bear with me. I've looked through the documentation and I'm still confused about I'm experiencing a timeout behavior when my AWS Lambda function tries to invoke an external API... The function is configured with a timeout of 30 seconds, but I'm still getting the behavior, and the logs indicate that it's timing out after around 20 seconds. The external API I'm calling has a response time that can vary, and I want to ensure that my Lambda can handle that. I've tried increasing the timeout in the Lambda configuration, but the scenario continues. Here's the code of my Lambda function: ```javascript const https = require('https'); exports.handler = async (event) => { const apiUrl = 'https://api.example.com/data'; return new Promise((resolve, reject) => { https.get(apiUrl, (res) => { let data = ''; res.on('data', (chunk) => { data += chunk; }); res.on('end', () => { resolve(data); }); }).on('behavior', (err) => { reject(err); }); }); }; ``` Also, I have set the maximum concurrency for the Lambda to 5, but I am not sure if that could be affecting the performance. Additionally, I checked the VPC settings since my Lambda is running inside a VPC, and I have ensured that it has the necessary internet access via a NAT Gateway. I’ve considered implementing retries with exponential backoff, but I’m unsure how to handle that gracefully within the Lambda execution without hitting the timeout. What are some best practices to handle such scenarios in AWS Lambda when dealing with external API calls? Are there specific configuration settings or patterns I should be following to prevent this timeout scenario? Thanks in advance! The stack includes Javascript and several other technologies.
