Incorrectly formatted links in link fields

[kevincrafts]

I came across a site this morning that was showing a "The website encountered an unexpected error. Try again later.

InvalidArgumentException: The URI 'www.colorado.edu/studentgroups/dsb' is invalid. You must use a valid URI scheme. in Drupal\Core\Url::fromUri() (line 293 of /code/web/core/lib/Drupal/Core/Url.php).

Because the url didn't include the "https://" the page would not render.

Is there a way to check link fields for incorrectly formatted urls?
