Go Lambda function no request body from docker - docker

Question

I am trying to deploy Go in a dockerized lambda function that responds to LambdaFunctionURLRequest. When I test locally I do not get the request body.
If I deploy a normal zip to lambda it works just fine.
I do get the error back and the docker does print
Here is the basic code + docker
main.go
package main
import (
"context"
"errors"
"log"
"net/http"
"time"
"github.com/aws/aws-lambda-go/events"
"github.com/aws/aws-lambda-go/lambda"
)
func main() {
lambda.Start(HandleRequest)
}
func init() {
log.Println("Init Function")
}
func HandleRequest(ctx context.Context, request events.LambdaFunctionURLRequest) (ev events.LambdaFunctionURLResponse, err error) {
log.Println("Received Handle Request")
log.Println(request.Body)
if request.Body == ""{
return ev, errors.New("No request body")
}
return
}
