The expression return self::getContainer()->get(App\Modules\Posts\Api\PostsApiInterface::class) could return the type null which is incompatible with the type-hinted return App\Modules\Posts\Api\PostsApiInterface. Consider adding an additional type-check to rule them out.

            $this->getContainer()->get(PostsApiInterface::class)

It seems like $this->getContainer()->get(App\Modules\Posts\Api\PostsApiInterface::class) can also be of type null; however, parameter $postsApi of App\Modules\Posts\Api\Command\BaselinePostsCommand::__construct() does only seem to accept App\Modules\Posts\Api\PostsApiInterface, maybe add an additional type check?
