Current Behavior The below code is causing the the program to crash:

package main

import (
	"context"
	"fmt"
	"net/url"
	"time"

	is "github.com/wabarc/archive.is"
)

func main() {
	wbrc := &is.Archiver{}
	url, _ := url.Parse(`https://gnu.org`)
	ctx, cancel := context.WithTimeout(context.Background(), 2*time.Minute)
	defer cancel()

	println("Archiving...")
	if result, err := wbrc.Wayback(ctx, url); err != nil {
		fmt.Printf("ERROR:  %v\n", err)
	} else {
		fmt.Printf("Success: %v\n", result)
	}
}

The TTY output:
