UnhandledPromiseRejectionWarning: TypeError: Cannot read property '0' of null

When I try to transform the following tags:

<meta property="og:title" content="V!RTL" />
<meta property="og:image" content="assets/logo.svg" />
<meta property="og:locale" content="en_US" />
<meta property="og:site_name" content="v1rtl.site" />

I get this error:

Thanks for submitting an issue.

From the readme:

This plugin uses the value of the og:url meta tag to convert og:image to an absolute URL.

You don't have an og:url meta tag so the plugin is throwing an error.

It would help if we checked for the tags and threw a more useful error explaining the issue. PR welcome.
