When I call the lambda.invoke using await the callback still appears to be called asynchronously. I'd like for the values I need to be available on the next line of code, hence the synchronous requirement. However, in the code below in the logs I see the "Data out of Callback" entry occur prior to the "Data in

My only question is: why 3GB? From where this number comes from? 回答1: The formula Projected peak

问题 I've been reading a lot on CORS/Lambda/AWS API Gateway configuration, including AWS's setup help: http://docs.aws.amazon.com/apigateway/latest/developerguide/how-to-cors.html And this great article: https://serverless.com/framework/docs/providers/aws/events/apigateway/ However, CORS is still defeating my API Gateway / Lambda function and I can't figure it out. Would love some help. The meat of it seems to be that API Gateway proxies the request onto Lambda and you need to set "Access-Control
