http.batch invalid method error

[artych]

Running the script:

import { group } from 'k6';
import http from 'k6/http';

export default function() {

  group("page_1", function() {
    http.batch([{
      url: "https://loadimpact.com/",
      method: "GET"
    }]);
  });
}

I get error:

ERRO[0032] GoError: net/http: invalid method "HTTPS://LOADIMPACT.COM/"

I wonder if arguments can be mixed up, and yes, after swapping the properties like:

    http.batch([{
      method: "GET",
      url: "https://loadimpact.com/"
    }]);

it works good.
