Cannot Buying ETH or other coins using Coinbase PHP API

Question

I am currently using Coinbase php API. I have try to buy ETH with the following code:

use Coinbase\Wallet\Client;
use Coinbase\Wallet\Configuration;
use Coinbase\Wallet\Resource;
use Coinbase\Wallet\Resource\Sell;
use Coinbase\Wallet\Resource\Buy;
use Coinbase\Wallet\Enum\Param;
use Coinbase\Wallet\Value\Money;
use Coinbase\Wallet\Resource\Account;
use Coinbase\Wallet\Enum\CurrencyCode;
use Coinbase\Wallet\Exception;
use GuzzleHttp\Exception\ClientException;
use Coinbase\Wallet\Resource\Transaction;


$configuration = Configuration::apiKey($apiKey, $apiSecret);
$client = Client::create($configuration);  

$accounts = $client->getAccounts();
$account = $client->getPrimaryAccount(); // or some other account

$buy = new Buy([
'amount' => new Money(0.05, CurrencyCode::ETH), 
'currency' => CurrencyCode::ETH
]);

$client->createAccountBuy($accounts, $buy, [Param::COMMIT => false]);
//$selldetail = $client->commitSell($sell);


$PaymentDetail = $client->decodeLastResponse();
//$PaymentArray =  $PaymentDetail['data'];


echo '<pre>';
print_r($PaymentDetail);
echo '</pre>';

The code is throwing this error:

Message Uncaught TypeError: Argument 1 passed to Coinbase\Wallet\Client::createAccountBuy() must be an instance of Coinbase\Wallet\Resource\Account, instance of Coinbase\Wallet\Resource\ResourceCollection given, called in C:\xampp\htdocs\dev\coinbase\cb_coin.php on line 154 and defined in C:\xampp\htdocs\dev\coinbase\src\Client.php:421 Stack trace: #0 C:\xampp\htdocs\dev\coinbase\cb_coin.php(154): Coinbase\Wallet\Client->createAccountBuy(Object(Coinbase\Wallet\Resource\ResourceCollection), Object(Coinbase\Wallet\Resource\Buy), Array) #1 {main} thrown

$accounts = $client->getAccounts(); returns a list, but $client->createAccountBuy expects only one account for the first parameter. You can either try to just do $accounts[0] to get the first one or print_r($accounts) and have a look which one you want to use.
