A single Adobe Commerce Cloud instance is configured with two websites, each containing one store view and using different domains.
- The default website is
website_one, with store view store_one and domain storeone.com.
- The second website is
website_two, with store view store_two and domain storetwo.com.
The magento-vars.php file is configured as follows to determine which website each request runs against:

During testing of a new GraphQL integration, every request returned data for the default website, irrespective of the domain.
What is the cause of this issue?
