InvalidArgumentException

I also have this issue with a basic page.

Created one MR from patch 2.
Branch: 3424320-invalidargumentexception-issue

Thanks, can we get this committed pls?

This looks good, Can we get a review?

Kindly address the feedback, and it should be good to go.

Hi.

I'm setting the issue status to Needs work because the merge request has merge conflicts that need to be resolved.

Additionally, there's a missing use statement in class Drupal\lang_dropdown\Plugin\Block\LanguageDropdownBlock — it's referencing an interface that does not exist or is not properly imported:

TypeError: Drupal\lang_dropdown\Plugin\Block\LanguageDropdownBlock::__construct(): Argument #10 ($route_match) must be of type Drupal\lang_dropdown\Plugin\Block\RouteMatchInterface, Drupal\Core\Routing\CurrentRouteMatch given, called in /lang_dropdown/src/Plugin/Block/LanguageDropdownBlock.php on line 121 in Drupal\lang_dropdown\Plugin\Block\LanguageDropdownBlock->__construct() (line 106 of /lang_dropdown/src/Plugin/Block/LanguageDropdownBlock.php).
