Undefined array key 0

[dietcheese]

Having a difficult time getting this working within Laravel.

Always getting a "Undefined array key 0" error. I am authenticating and getting an access token successfully.

Part of my class:

use Sugarcrm\REST\Client\SugarApi;
use Illuminate\Support\Facades\Config;
use Illuminate\Support\Facades\Log;

class SugarCRMService
{
    protected $client;
    protected $server;
    protected $credentials;

    public function __construct()
    {
        // Retrieve server URL and credentials from config (which pulls from .env)
        $this->server = Config::get('services.sugarcrm.url');
        $this->credentials = [
            'username'  => Config::get('services.sugarcrm.username'),
            'password'  => Config::get('services.sugarcrm.password'),
            'platform'  => Config::get('services.sugarcrm.platform'),
            'client_id' => Config::get('services.sugarcrm.client_id'),
        ];
        
        Log::info('Initializing SugarCRM Service', $this->credentials);
        
        try {
            // Instantiate the SugarApi client using the server URL and credentials.
            $this->client = new SugarApi($this->server, $this->credentials);
            
            // Check if the client is authenticated; if not, log in.
            if (!$this->client->isAuthenticated()) {
                $this->client->login();
            }
            
            // Log the token details (printing only the access_token for brevity)
            $token = $this->client->getAuth()->getToken();
            Log::info('Logged into SugarCRM', [
                'access_token' => $token->access_token,
                'expiration'   => $token->expiration,
            ]);
        } catch (\Exception $e) {
            Log::error('Failed to initialize SugarCRM client', [
                'message' => $e->getMessage(),
                'trace'   => $e->getTraceAsString(),
            ]);
            throw $e;
        }
    }

public function testAccount(string $accountId = 'be46e9f4-27e2-4357-9af4-b18039e1f231'): array
    {
        try {
            // Ensure the client is authenticated.
            if (!$this->client->isAuthenticated()) {
                $this->client->login();
            }
            
            // Build the custom endpoint URL.
            $endpoint = 'custom/account/' . $accountId;
            
            // Call the endpoint using the built-in get() method.
            $response = $this->client->get($endpoint);
            
            Log::info('Received response from testAccount', [
                'endpoint' => $endpoint,
                'response' => $response->toArray(),
            ]);
            
            return $response->toArray();
        } catch (\Exception $e) {
            Log::error('Failed testAccount call', [
                'endpoint' => 'custom/account/' . $accountId,
                'error'    => $e->getMessage(),
                'trace'    => $e->getTraceAsString(),
            ]);
            throw $e;
        }
    }
}

It should be noted that when I use Guzzle instead, the same endpoint works fine:

         // Create a new Guzzle client.
            $guzzleClient = new GuzzleClient();
            
            // Make a GET request with the OAuth token set in headers.
            $response = $guzzleClient->request('GET', $url, [
                'headers' => [
                    'OAuth-Token' => $this->client->getAuth()->getToken()->access_token,
                ]
            ]);
            
            // Decode the response JSON.
            $data = json_decode($response->getBody()->getContents(), true);
            
            Log::info('Received response from testAccount (raw request)', [
                'url'  => $url,
                'data' => $data,
            ]);
