I am trying to consume PokeAPI using Drupal. For making API calls I am using HTTP Client Manager module. I am able to set up initial configuration and get the data when the response field is a string. But I am not able to get data when the response field is array.Can any one please point out what I am doing wrong.

I am just trying to make a HttpGet request to the following URL

https://pokeapi.co/api/v2/pokemon?offset=300&limit=100

As the API has documentation of their resource Documentation I felt it would be good until I hit the wall of dealing with Array field. If anyone got suggestion for better approach I would like to try it out.

My code is as follows :

pokeapi/pokeapi.http_services_api.yml

pokeapi.base:   title: "Drupal and PokeAPI Services API"   api_path: "src/api/pokeapi_services.yml"   config:     base_uri: "https://pokeapi.co/"     debug: "/tmp/pokeapi.log"

pokeapi/src/api/resources/posts.yml

pokeapi/src/Controller/PokeAPIController.php

<?php  namespace DrupalpokeapiController;  use DrupalCoreControllerControllerBase; use Drupalhttp_client_managerHttpClientInterface; use SymfonyComponentDependencyInjectionContainerInterface;  /**  * Returns responses for PokeAPI routes.  */ class PokeAPIController extends ControllerBase {    /**    * PokeAPI Http Client.    *    * @var Drupalhttp_client_managerHttpClientInterface    */   protected $httpClient;    /**    * {@inheritdoc}    */   public function __construct(HttpClientInterface $http_client) {     $this->httpClient = $http_client;   }    /**    * {@inheritdoc}    */   public static function create(ContainerInterface $container) {     return new static(       $container->get('pokeapi.http_client')     );   }    /**    * Get Client.    *    * @return Drupalhttp_client_managerHttpClientInterface    *   The Http Client instance.    */   public function getClient() {     return $this->httpClient;   }    /**    * Builds the response.    */   public function build() {      $client = $this->getClient();     $command = 'GetPokemonsList';      $response = $client->call($command)->toArray();     dpm($response);      $build['content'] = [       '#type' => 'item',       '#markup' => $this->t('It works!'),     ];      return $build;   }  } 

result of dpm($response);

Array (     [0] => 1118     [1] => https://pokeapi.co/api/v2/pokemon?offset=300&limit=100     [2] => https://pokeapi.co/api/v2/pokemon?offset=100&limit=100     [3] => Array         (         )  ) 

here array value indexed 3 in response should contain result array of the data.

I believe there is some error in the following definition in the posts.yml If anyone can point out the correct way it will be helpful.

      results:         location: "json"         type: "array"         items:           "$ref": "DetailedResourceList"    DetailedResourceList:
