[steverobbins]

Preconditions (*)

1. Magento 2.4.7-p7
2. Module 1.6.4

Steps to reproduce (*)

1. Place an order

Expected result (*)

1. View the success page

Actual result (*)

1. The Magento error page is shown, "There has been an error processing your request"
2. The error in the report is Warning: Undefined array key 104 in /var/www/deploy/releases/20251112204937/vendor/meta/module-conversion/Model/Tracker/Purchase.php on line 189

This is the line of code causing the error

meta-for-magento2/app/code/Meta/Conversion/Model/Tracker/Purchase.php

Lines 184 to 191 in eef709e

	if ($order->getCustomerGender()) {
	$genderId = $order->getCustomerGender();
	$userData[AAMSettingsFields::GENDER] =
	$this->magentoDataHelper->hashValue(
	$this->customerMetadata->getAttributeMetadata('gender')
	->getOptions()[$genderId]->getLabel()
	);
	}

There probably needs to be an additional condition to make sure the $genderId exists in the array before calling the ->getLabel() method, for example:

if ($order->getCustomerGender()) {
    $genderId = $order->getCustomerGender();
    $gender = $this->customerMetadata->getAttributeMetadata('gender')
        ->getOptions()[$genderId] ?? false;
    if ($gender) {
        $userData[AAMSettingsFields::GENDER] =
            $this->magentoDataHelper->hashValue($gender->getLabel());
    }
}

FYI, these are the values for my customer gender attribute. This is where the 104 is coming from in the error message.

select ea.attribute_id
  , ea.entity_type_id
  , ea.attribute_code
  , eao.option_id
  , eaov.value
from eav_attribute ea
inner join eav_attribute_option eao on ea.attribute_id = eao.attribute_id
inner join eav_attribute_option_value eaov on eao.option_id = eaov.option_id
where ea.attribute_code = 'gender'

attribute_id	entity_type_id	attribute_code	option_id	value
20	1	gender	104	Male
20	1	gender	105	Female
