wish helps you the issue with your code is when you query data from Postgres, Eloquent return you a Collection object instead of a JSON string. Therefore, the line:
code :
$results = json_decode($articles, true);
$results = $articles->map(function($article){
   return [
      'id' => $article->id,
      'data' => json_decode($article->data, true)  
   ];
})
