Go Lambda function no request body from docker

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
}

Docker
