Exception #0 (Magento\Framework\Exception\LocalizedException): More than one node matching the query: /config/zip[@countryCode='US']/codes/code

Question

PHP 7.0.22 and Magento 2.1.3

When I'm trying to add a customization to the US zipcodes masks, Magento throws out an exception Exception #0 (Magento\Framework\Exception\LocalizedException): More than one node matching the query: /config/zip[@countryCode='US']/codes/code

I followed throughly the documentation Add custom input mask for ZIP code but still not getting it working.

This is my app/code/Test/Directory/etc/zip_codes.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Directory:etc/zip_codes.xsd">
    <zip countryCode="US">
        <codes>
            <code id="pattern_3" active="true" example="Any character [a-z]">^[a-z]+$</code>
        </codes>
    </zip>
</config>

This is the error trace:

This issue has been solved in release 2.2, as mentioned here by a Magento core member, on the commit 4ddb336.

The file app/code/Magento/Directory/Model/Country/Postcode/Config/Reader.php should be:

protected $_idAttributes = [
    '/config/zip' => 'countryCode',
    '/config/zip/codes/code' => 'id',
];
