Cannot get Recommendations of different model types.

[RaidOuahioune]

I have a table called user_views like shown bellow

And here is the code to config the recommendation i used

<?php

namespace App\Business\Recommendation;

use App\Models\Course;
use App\Models\Document;
use App\Models\Question;

trait HasViewsRecommendation
{


    public static $recommendations = [
        Document::class => 'suggested_documents',
        Course::class => 'suggested_courses',
        Question::class => 'suggested_questions'
    ];

    public static $recommendationCount = 5;
    private static function generateRelationAlgorithmArray(string $model, string $name): array
    {

        return
            [$name => [
                'recommendation_algorithm'         => 'db_relation',
                'recommendation_data_table'        => 'user_views',
                'recommendation_data_table_filter' => [],
                'recommendation_data_field'        => 'viewable_id',
                'recommendation_data_field_type'   => $model,
                'recommendation_group_field'       => 'user_id',
                'recommendation_count'             => self::$recommendationCount
            ]];
    }
    public static function getRecommendationAlgorithmArray(): array
    {
        $result = [];
        foreach (self::$recommendations as $model => $name) {
            $result = array_merge($result, self::generateRelationAlgorithmArray($model, $name));
        }
        return $result;
    }
}

And for sure I overided the the static function like this

class User extends Authenticatable implements  InteractWithRecommendation
{

    use HasFactory,
        HasRecommendation,
        HasViewsRecommendation,
  

    /**
     * The user recommendation config.
     * @return array
     */
    public static function getRecommendationConfig(): array
    {
        return self::getRecommendationAlgorithmArray();
    }

And i generated some recommendations using the laravel-model-recommendation table and here is some rows

Now based on my understanding .if the user logged in is of id 7 and i called the fuction php $user->getRecommendations('suggested_courses'); I should get the First 5 rows that are of type Courses .But the thing is that i always get an empty array .
To better undestand the situation I inspected the source code and I think it"s because of this query

The target_type is hardcoded to be the same as the source type.
