The error message suggests that the WarehouseCalloutService class has not run successfully. Although the code may show as successful, there could be issues that are causing the class not to run correctly. Here are a few things you can check to resolve the issue:
Verify that the class is correctly implemented and meets all necessary requirements for a Queueable class.
Check if the class is properly enqueued and the code is executing as expected.
Ensure that all required methods, variables and properties are properly defined and referenced within the class.
Debug the code by adding System.debug statements to see where the error is occurring.
