Reproduction code:

	$exchange = new $id();
	$exchange->apiKey = "XXXX"; // let me know if you need temporary API key, I can make it for testing
	$exchange->secret = "YYYY";
	$exchange->enableRateLimit = true;

	$balance = $exchange->fetchBalance();
} catch (\ccxt\ExchangeError $e) {
	echo '[Exchange Error] ' . $e->getMessage();
	print_r($e);
}

I see, my manual script patching approach caused the above error. Updating CCXT to 1.66.70 fixed the issue and crypto.com is working well now. Thank you!

@c0dehunter you should also update the base files as well, make sure that your runtime CCXT version number in your script is 1.66.70+. (We’ve tested on our side and it should work for you as well).
