6.1.1 Products sync error (related to contextual pricing countries)

[smcyr]

Description

We updated the Sophify plugin to 6.1.1 and when syncing products from Shopify, we now have this error:

2025-12-10 09:12:08 [web.ERROR] [TypeError] craft\helpers\StringHelper::toUpperCase(): Argument #1 ($str) must be of type string, null given, called in /var/www/website/vendor/craftcms/shopify/src/models/Settings.php on line 244 {"trace":["#0 /var/www/website/vendor/craftcms/shopify/src/models/Settings.php(244): craft\\helpers\\StringHelper::toUpperCase()","#1 /var/www/website/vendor/craftcms/shopify/src/services/Api.php(189): craft\\shopify\\models\\Settings->getContextualPricingCountries()","#2 /var/www/website/vendor/craftcms/shopify/src/services/Products.php(80): craft\\shopify\\services\\Api->getProductGql()","#3 /var/www/website/vendor/craftcms/shopify/src/handlers/Webhook.php(27): craft\\shopify\\services\\Products->syncProductByShopifyId()","#4 /var/www/website/vendor/shopify/shopify-api/src/Webhooks/Registry.php(159): craft\\shopify\\handlers\\Webhook->handle()","#5 /var/www/website/vendor/craftcms/shopify/src/controllers/WebhookController.php(43): Shopify\\Webhooks\\Registry::process()","#6 [internal function]: craft\\shopify\\controllers\\WebhookController->actionHandle()","#7 /var/www/website/vendor/yiisoft/yii2/base/InlineAction.php(57): call_user_func_array()","#8 /var/www/website/vendor/yiisoft/yii2/base/Controller.php(178): yii\\base\\InlineAction->runWithParams()","#9 /var/www/website/vendor/yiisoft/yii2/base/Module.php(552): yii\\base\\Controller->runAction()","#10 /var/www/website/vendor/craftcms/cms/src/web/Application.php(360): yii\\base\\Module->runAction()","#11 /var/www/website/vendor/craftcms/cms/src/web/Application.php(659): craft\\web\\Application->runAction()","#12 /var/www/website/vendor/craftcms/cms/src/web/Application.php(322): craft\\web\\Application->_processActionRequest()","#13 /var/www/website/vendor/yiisoft/yii2/base/Application.php(384): craft\\web\\Application->handleRequest()","#14 /var/www/website/web/index.php(12): yii\\base\\Application->run()","#15 {main}"],"memory":3445992,"exception":"[object] (TypeError(code: 0): craft\\helpers\\StringHelper::toUpperCase(): Argument #1 ($str) must be of type string, null given, called in /var/www/website/vendor/craftcms/shopify/src/models/Settings.php on line 244 at /var/www/website/vendor/craftcms/cms/src/helpers/StringHelper.php:1775)"}

It seems related to the fact that "Contextual Pricing Countries" is empty in our settings.

Steps to reproduce

1. Start a Shopify sync with no value in "Contextual Pricing Countries"
2. See a server error
