Deprecated function: Return type of Drupal\matomo\Component\Render\MatomoJavaScriptSnippet::jsonSerialize() should either be compatible with JsonSerializable::jsonSerialize(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in include() (line 12 of modules/matomo/src/Component/Render/MatomoJavaScriptSnippet.php).
