aws-api-gateway

I am trying to set up a hello world example with AWS lambda and serving it through api gateway. I clicked the "Create a Lambda Function", which set up the api gatway and selected the Blank Function option. I added the lambda function found on AWS gateway getting started guide : exports.handler = function(event, context, callback) { callback(null, {"Hello":"World"}); // SUCCESS with message }; The issue is that when I make a GET request to it, it's returning back a 502 response { "message": "Internal server error" } . And the logs say "Execution failed due to configuration error: Malformed

For instance if I want to return a specific 400 error for invalid parameters or perhaps a 201 when the lambda function call resulted in a create. I'd like to have different http status codes but it looks like api gateway always returns a 200 status code even if the lambda function is returning an error. Update per 20-9-2016 Amazon finally made this easy using the Lambda Proxy integration . This allows your Lambda function to return proper HTTP codes and headers: let response = { statusCode: '400', body: JSON.stringify({ error: 'you messed up!' }), headers: { 'Content-Type': 'application/json',

I have 2 Lambda functions - one that produces a quote and one that turns a quote into an order. I'd like the Order lambda function to call the Quote function to regenerate the quote, rather than just receive it from an untrusted client. I've looked everywhere I can think of - but can't see how I'd go about chaining or calling the functions...surely this exists! I found a way using the aws-sdk . var aws = require('aws-sdk'); var lambda = new aws.Lambda({ region: 'us-west-2' //change to your region }); lambda.invoke({ FunctionName: 'name_of_your_lambda_function', Payload: JSON.stringify(event,
