Problem/Motivation

When using PHP 8.1 the following error is displayed:

Deprecated function: preg_quote(): Passing null to parameter #1 ($str) of type string is deprecated in Drupal\Core\Path\PathMatcher->matchPath() (line 82 of core/lib/Drupal/Core/Path/PathMatcher.php).
Drupal\Core\Path\PathMatcher->matchPath('/admin/config', NULL) (Line: 1433)
mailchimp_page_bottom(Array) (Line: 355)
Drupal\Core\Render\MainContent\HtmlRenderer->buildPageTopAndBottom(Array) (Line: 150)

Steps to reproduce

  1. Using Drupal 9.3.12
  2. With PHP 8.1
  3. Install mailchimp module
  4. Configure mailchimp module
  5. Enable 'Enable connected site' - but without connecting this site to Mailchimp first!
  6. When viewing any page the warning will be displayed.

Proposed resolution

Check if $connected_site_paths is not null before testing the paths.
