Warning: Undefined array key "custom"

[gjuric]

I am not sure this is the right venue to address the issue, but since today we started having warnings issued when adding custom attributes to a customer.

Warning: Undefined array key "custom"

The warning is issued when calling Customer::addCustomAttributes() here:

chartmogul-php/src/Customer.php

Lines 285 to 298 in e658322

	public function addCustomAttributes($custom)
	{
	$result = $this->getClient()
	->send(
	'/v1/customers/'.$this->uuid.'/attributes/custom',
	'POST',
	[
	'custom' => func_get_args()
	]
	);
	$this->attributes['custom'] = $result['custom'];
	return $result['custom'];
	}

It looks like the response doesn't receive the custom value that was set.

Problem started occurring today around 10:30 CEST.
