Motivation and Context

Based on thediscussion at the time of closing Issue#557, here are some basic test cases that address edge cases related to object types and UUID keys.
These tests could be useful for future development if any changes occur in the relevant classes, ensuring a smooth flow for handling UUIDs and object keys.
