Exception: The scheme href='https is invalid.

I'm getting a lot of errors related to the URI lib, such as:
Exception: The scheme `href='https` is invalid. /home/[...REMOVED...]/public_html/application/third_party/Readability.php/v3.1.2/vendor/league/uri/src/Uri.php 249

Thanks for reporting this @jeffbotw. Are you able to provide the code you used that led to the error so we can try to reproduce it. If not, can you provide the URL of the page which caused the error?

We were able to reproduce this. It ocurred when Readability.php was set to rewrite relative URLs:

$configuration = new Configuration();
$configuration
    ->setFixRelativeURLs(true)
    ->setOriginalURL('http://example.com/article.html');
$readability = new Readability($configuration);

and the HTML being parsed contained invalid URL, e.g.

<article>
    <h1>Title</h1>
    <p>Paragraph of text.</p>
    <p>Paragraph with bad link: <a href="href='https:/bad'">test</a></p>
</article>

Fixed in 3.1.3: https://github.com/fivefilters/readability.php/releases/tag/v3.1.3
