kong.Response.Exit() Hanging

[joeyagreco-sb]

When calling Response.Exit(), code hangs.

Example for reproduction:

Set shouldExit to true, and the test hangs.
Set shouldExit to false and the test does not hang.

package main

import (
	"errors"
	"fmt"
	"net/http"
	"testing"

	"github.com/Kong/go-pdk"
	"github.com/stretchr/testify/assert"

	k "github.com/Kong/go-pdk/test"
)

type foo struct {
	shouldExit bool
}

func New() *foo {
	return &foo{
		// manually change me to see both ways
		shouldExit: true,
	}
}

func (f *foo) Response(kong *pdk.PDK) {
	if f.shouldExit {
		fmt.Println("im trying to exit early")
		kong.Response.Exit(http.StatusInternalServerError, []byte(errors.New("exit").Error()), nil)
	}
	fmt.Println("im done")
}

func TestFoo(t *testing.T) {
	t.Parallel()

	env, err := k.New(t, k.Request{
		Method: "POST",
		Url:    "",
		Body:   []byte("{}"),
	})
	assert.NoError(t, err)
	env.DoHttps(New())
}

I will note that kong.Response.ExitStatus() does not hang.
