Bybit testnet issue with create_order, "ret_code":10004

• OS: CENTOS 7.9
• Programming Language version: PHP 7.4.18
• CCXT version: 1.49.61

My code:

require __DIR__ . '/../vendor/autoload.php';
$exchange = new \ccxt\bybit(array(
    'apiKey' => 'key-here',
    'secret' => 'secret-here',
    'timeout' => 30000,
    'enableRateLimit' => true,
));
$exchange->set_sandbox_mode(true);
echo "CCXT version: " . \ccxt\Exchange::VERSION . "<br />";
$markets = $exchange->load_markets(); // load all markets
$exchange->verbose = true;

$order = $exchange->create_order('XRP/USD', 'limit', 'buy', 3, 1.5274);

Output:

CCXT version: 1.49.61
