Checkout new field not working

[nervusdm]

Hey !

My code works on my dev machine and not on production, sadly. (really sadly).

The module is about adding a dropdown on checkout page on the ship address page.

Here is my di.xml

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">


     <type name="Magento\Checkout\Model\ShippingInformationManagement">
        <plugin name="magasin_address_save_plugin" type="Vendor\MagasinSelector\Plugin\MagasinOrderPlugin" sortOrder="10"/>
    </type>
<type name="Magento\Sales\Api\OrderRepositoryInterface">
    <plugin name="get_order_magasin_id" type="Vendor\MagasinSelector\Plugin\OrderGet"/>
</type>
    <type name="Magento\Checkout\Block\Checkout\LayoutProcessor">
        <plugin name="magasin_selector" type="Vendor\MagasinSelector\Plugin\MagasinPlugin" sortOrder="100" />
    </type>
</config>

MagasinPlugin.php :

<?phpnamespace HexaPlus\MagasinSelector\Plugin;
use Magento\Checkout\Block\Checkout\LayoutProcessor;
use MageClass\ClickAndCollect\Model\Store;

class MagasinPlugin 
{
    public function afterProcess(LayoutProcessor  $subject, $jsLayout) {


        $customAttributeCode = 'magasin_id';        $customField = [
            'component' => 'Magento_Ui/js/form/element/select',
            'config' => [
                'customScope' => 'shippingAddress.custom_attributes',
                'template' => 'ui/form/field',
                'elementTmpl' => 'ui/form/element/select',
                'id' => 'drop-down2',
            ],
            'dataScope' => 'shippingAddress.custom_attributes.magasin_id',
            'label' => 'Sélectionner Votre magasin conseil (cela ne sera pas forcément votre lieu de livraison)',
            'provider' => 'checkoutProvider',
            'visible' => true,
            'validation' => ['required-entry' => true],
            'sortOrder' => 150,
            'id' => 'drop-down2',
            'options' => $options
        ];        $jsLayout['components']['checkout']['children']['steps']['children']['shipping-step']['children']['shippingAddress']['children']['shipping-address-fieldset']['children'][$customAttributeCode] = $customField;

        return $jsLayout;
    }
}



?>

(I removed the $options part). It works on dev, same version 2.2.6 it doesnt work on prod ! I have no idea why.

Most interessting part : If I copy & paste the .di xml inside one other module, it works..

I tried everything : removed generation folder. cache clean. di:compile..

What I am doing wrong ?

Thanks you
