调用未定义的方法 GuzzleHttp\Command\Result::getBody()

Question

I am trying to get a response in Drupal from an outside API in json format. I am using HTTP Client Manager Drupal module. Right now I can only get response in stdClass Object format in Array and all the response key values are missing.

My original code:

public function findPosts() {
    $client = $this->getClient();
    $params = array('client_Id' => "12345",
    "client_Secret" => "42452454",
    "scope" => "read");

      $response = $client->FindPosts($params);

      dpm($response);

    return ['#markup' => $response];
  }

Outputs the code below. What I need it too look like is [access_token] => eyJhbGciOiJIUzUxMiIsIn, [type] => bearer, etc.

stdClass Object
(
    [__CLASS__] => GuzzleHttp\Command\Result
    [data:protected] => Array
        (
            [0] => eyJhbGciOiJIUzUxMiIsIn
            [1] => bearer
            [2] => 3600
            [3] => 2022-11-09T10:48:47+00:00
            [4] => read
            [5] => MwA1ADkAZAA0AGIAZAA4AC0AOQAzADcA
            [6] => 86400
            [7] => 2022-11-10T09:48:47+00:00
        )

)

When I try $response->getBody() or $response->getContent(), or any other response method it returns the error below.

Error: Call to undefined method GuzzleHttp\Command\Result::getBody() in Drupal\http_client_manager_example\Controller\ExampleController->findPosts() (line 92 of modules/contrib/http_client_manager/modules/http_client_manager_example/src/Controller/ExampleController.php).

As @bwaindwain mentioned toArray() method works instead of getBody() .

toArray() method works wells with responses in format:

[
    {
      "token": "4354iojegdjss"
    }
]

However, with this response format all keys still disappear:

 {
      "token": "4354iojegdjss"
 }   

My fix for this issue is to manually add responseModel in src/api/resources/posts.json this way:

{
  "operations": {
    "GetToken": {
      "httpMethod": "POST",
      "uri": "token",
      "summary": "Get token",
      },
      "responseModel": "Token"
  }
}

 "models": {
    "Token": {
      "type": "object",
      "location": "json",
      "properties": {
        "token": {
          "location": "json",
          "type": "string"
        }
       }
    }
 }

If somebody knows a better fix, please, comment.
