Error: The onCancel handler was attached after the promise settled.

I get the following for new Sitemapper({ url: 'https://www.google.com/sitemap.xml' }):

Error: The `onCancel` handler was attached after the promise settled.

Hey @WillSquire will take a look here, what version are you using?

@WillSquire if you have a stacktrace this would be helpful too, and you can also add a debug flag to see more details

new Sitemapper({ url: 'https://www.google.com/sitemap.xml', debug: true });

I just ran this on the latest version and it works okay:

const Sitemapper = require("sitemapper");

const sitemap = new Sitemapper({
  url: "https://www.google.com/sitemap.xml",
  debug: true,
});

sitemap.fetch().then((results) => console.log(results.sites));
