调用Gateway API Go函数时在AWS Lambda中获取PathError

I'm setting up a AWS Lambda function that runs Go 1.x that I call with a web hook on a form submit on my website. This is the AWS Designer and Gateway POST request

When I call the Gateway API Gateway API Endpoint I get a return of errorMessage":"fork/exec /var/task/WebhookForm: no such file or directory","errorType":"PathError the WebhookForm is the function that I should be invoking but I can't seem to figure this problem out.

//WebhooksForm/main.go
package main

import (
    "context"
    "fmt"
    "log"
    "net/smtp"

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

func HandleRequest(ctx context.Context, name MyEvent) (string, error) {
    return fmt.Sprintf("Hello!"), nil
}

func main() {
    lambda.Start(HandleRequest)
}
