Build it for AWS Lambda

It needs different build and parameters so it can be run on AWS

GOOS=linux GOARCH=amd64 CGO_ENABLED=0 go build -o main main.go

Zip it

zip main.zip main

Troubleshooting

Lambda path error

"errorMessage" => "fork/exec /var/task/main: exec format error", "errorType" => "PathError"}

This means your build doesn't work with AWS Lambda, please build it with the env written above
