Order book requests are not working

[tistis96]

I have this code:

<?php
require __DIR__ . '/vendor/autoload.php';

use Soneso\StellarSDK\StellarSDK;
use Soneso\StellarSDK\Asset;

$sdk = StellarSDK::getPublicNetInstance();

$sellingAsset = Asset::createNonNativeAsset('yXLM', 'GARDNV3Q7YGT4AKSDF25LT32YSCCW4EV22Y2TV3I2PU2MMXJTEDL5T55');
$orderBook = $sdk->orderBook()->forBuyingAsset(Asset::native())->forSellingAsset($sellingAsset)->limit(1)->execute();
$offerAmount = $orderBook->getBids()->toArray()[0]->getAmount();
$offerPrice= $orderBook->getBids()->toArray()[0]->getPrice();

When I try to send a request to order book, I encounter this error:

PHP Fatal error: Uncaught Error: Typed property Soneso\StellarSDK\Responses\OrderBook\OrderBookResponse::$bids must not be accessed before initialization in C:\Users\USER\Desktop\projects\vendor\soneso\stellar-php-sdk\Soneso\StellarSDK\Responses\OrderBook\OrderBookResponse.php:50

The problem persist on getBids() method. I also ran the test from StellarSDKTests/TradesTest.php and it passes succesfully.

I'm using:

• windows 10;
• php version 8.1.1

Hello @tistis96,
thank you for reporting this issue. I fixed it in this commit :0f7edb1
it is published in release 0.4.0
pls. update your sdk version and try again.

That same code crashes with error 500 for me. I have my php file in the directory above /vendor/.

<?php
require __DIR__ . '/vendor/autoload.php';
//or this
//require 'vendor/autoload.php';

use Soneso\StellarSDK\StellarSDK;
use Soneso\StellarSDK\Asset;

$sdk = StellarSDK::getPublicNetInstance();

$sellingAsset = Asset::createNonNativeAsset('yXLM', 'GARDNV3Q7YGT4AKSDF25LT32YSCCW4EV22Y2TV3I2PU2MMXJTEDL5T55');
$orderBook = $sdk->orderBook()->forBuyingAsset(Asset::native())->forSellingAsset($sellingAsset)->limit(1)->execute();
$offerAmount = $orderBook->getBids()->toArray()[0]->getAmount();
$offerPrice= $orderBook->getBids()->toArray()[0]->getPrice();
