Newsletter subscription in registration form not working

[arutr]

One of the plugins in this module, which injects into customer extension attributes, breaks signing up for the newsletter when registering a customer account:

magento/Extensions/Customer.php

Lines 42 to 50 in fb9f5f9

	$subscriber = $this->subscriberResource->loadBySubscriberEmail(
	$customer->getEmail(),
	(int)$this->storeManager->getStore($customer->getStoreId())->getWebsiteId()
	);
	$subscriberStatus = !empty($subscriber['subscriber_status']) ? (int)$subscriber['subscriber_status'] : 0;
	$isSubscribed = $subscriberStatus === SubscriberModel::STATUS_SUBSCRIBED;
	$extension->setIsSubscribed($isSubscribed);
	$customer->setExtensionAttributes($extension);

When creating an account, is_subscribed is set to 1. Currently this code sets it to 0 as $subscriber is empty, which prevents signing up for the newsletter later on in the code.

To fix this, after loading $subscriber, we need to check whether the array has data. If it doesn't, then we return $extension:

         $subscriberStatus = !empty($subscriber['subscriber_status']) ? (int)$subscriber['subscriber_status'] : 0;
         $isSubscribed = $subscriberStatus === SubscriberModel::STATUS_SUBSCRIBED;
         $extension->setIsSubscribed($isSubscribed);
