Hi,

I'm trying to get apex/gateway to work, however the provided example doesn't really work:

apex ᐅ export GO111MODULE=on
apex ᐅ cat main.go
package main

import (
        "fmt"
        "log"
        "net/http"

        "github.com/apex/gateway"
        "github.com/aws/aws-lambda-go"
)

func main() {
        http.HandleFunc("/", hello)
        log.Fatal(gateway.ListenAndServe(":3000", nil))
}

func hello(w http.ResponseWriter, r *http.Request) {
        // example retrieving values from the api gateway proxy request context.
        requestContext, ok := gateway.RequestContext(r.Context())
        if !ok || requestContext.Authorizer["sub"] == nil {
                fmt.Fprint(w, "Hello World from Go")
                return
        }

        userID := requestContext.Authorizer["sub"].(string)
        fmt.Fprintf(w, "Hello %s from Go", userID)
}
apex ᐅ go build main.go
go: finding github.com/aws/aws-lambda-go/events latest
go: finding github.com/aws/aws-lambda-go/lambda latest
build command-line-arguments: cannot load github.com/aws/aws-lambda-go: cannot find module providing package github.com/aws/aws-lambda-go

Any ideas? Thanks in advance.

BR,
Victor
