No blocks displayed

Hi, to be able to help you I need the drupal and module version you’re using as well as the errors that are in the logs and/or on screen.

The site where I want to use the Google reviews module
Core version: 9.4.10
Google reviews version: 1.1.2

simplytest.me test:
Core version: 9.5.8
Google reviews version: 1.1.2

I also tried changing the code on the site where I can access the code of the module. I modified the build() functions of the blocks, but the blocks still don't appear:
GoogleReviewsBlock.php:

  public function build() {
/*
    $config = $this->getConfiguration();
    $reviews = $this->getGoogleData->getGoogleReviews(['rating', 'reviews'], $config['max_google_reviews'], $config['google_reviews_sorting']);
    if (!empty($reviews)) {
      $renderable = [
        '#attached' => ['library' => ['googlereviews/googlereviews.reviews']],
        '#theme' => 'googlereviews_reviews_block',
        '#reviews' => $reviews['reviews'],
        '#place_id' => $reviews['place_id'],
      ];

      return $renderable;
    }
*/
return ['#markup' => t('GoogleReviewsBlock')];
  }

GoogleRatingBlock.php:

  public function build() {
/*
    $rating = $this->getGoogleData->getGoogleReviews([
      'rating',
      'user_ratings_total',
    ]);

    if (!empty($rating)) {
      $rating_percentage = ($rating['rating'] / 5) * 100;

      $renderable = [
        '#attached' => ['library' => ['googlereviews/googlereviews.rating']],
        '#theme' => 'googlereviews_rating_block',
        '#user_ratings_total' => $rating['user_ratings_total'],
        '#rating' => $rating['rating'],
        '#rating_percentage' => $rating_percentage,
        '#place_id' => $rating['place_id'],
      ];

      return $renderable;
    }
*/
    return ['#markup' => t('GoogleRatingBlock')];
  }

Can you tell me what’s in the error logs on the site and php error logs on the server where you can access the code?

There are no error message on the screen nor in the logs...

I'm sorry for your invested time and attention... The source of the problem is the bad configuration on the Google Maps API, and Place api side
I don't know what's wrong yet, but probably your module works properly

Thank you!

I just tested it with the Drupal version you used and indeed found it it's working normally.
Good luck!
