问题 I have an API Gateway with an endpoint that is fulfilled by AWS Lambda proxy integration. I have also configured a custom authorizer for this endpoint. I am seeing an issue where the first request that I make to this endpoint is successful, but additional calls will fail; I get a 403 - Forbidden error. If I wait a while, I can make another request that succeeds but then I start seeing the same problem. Here's my code for the authorizer: const jwt = require('jsonwebtoken'); exports.authorizer

问题 When uploading a python zip package to AWS Lambda from S3 I get the following cryptic error: module initialization error: [Errno 13] Permission denied: '/var/task/lambda_function.py' The error seems to be that if you create a zip package with restrictive permissions, then AWS gets confused. Essentially, AWS unzips your package with the permissions you gave it and tries to use it. What can make this especially confusing is that you may be able to see part of the zip files from the AWS Lambda

问题 I have a Ruby Lambda function which depends on an external (ie non-AWS) RubyGem. I have a Gemfile , a Gemfile.lock and a vendor/bundle directory. Everything looks fine from a local perspective. I've tried using bundle install --path vendor/bundle and bundle install --deployment to install the gems, and am specifically including the vendor directory when zipping up the files: zip -r function.zip myfunction.rb vendor Despite this, when I test the function in the Lambda console, it's failing

问题 I am creating a DeepLens project to recognise people, when one of select group of people are scanned by the camera. The project uses a lambda, which processes the images and triggers the ' rekognition ' aws api. When I trigger the API from my local machine - I get a good response When I trigger the API from AWS console - I get failed response Problem After much digging, I found that the 'boto3' (AWS python library) is of version: 1.9.62 - on my local machine 1.8.9 - on AWS console Question

问题 Inside a certain function I want to stop the whole Lambda process but not trigger an error. I've tried looking at the context variable to stop it or just calling exit() but each time it's treated as an error which I don't want to track. How can I end successfully a Lambda process in Python? 回答1: In AWS Lambda you define a handler function and in Python a function just needs to return in order to complete successfully, where return implies return None . What you've done is correct, just have

问题 I want to connect my Lambda function to Mongo Atlas. It was all working fine but I needed to move my function inside a VPC so I could use redis. Now I cannot connect to my database. I looked at the security group on the VPC and added the mongo db port but with no joy Also - the mongo IP Whitelist is as follows for now 0.0.0.0/0 (includes your current IP address) Is there anything else I should try? Thank you 回答1: I needed to move my function inside a VPC so I could use redis. If you are:
