Not able to use Find Object and call object method in keyword tests to validate data

The methods that you use, you should read the documentation of Result Value that's returned.

For example, if the property checkpoint value matches, the checkpoint logs a success message, otherwise, it logs an error message. It does not throw an error. If the Find method does not match the search criteria, it returns a stub object that only contains the Exists property equal to False. It does not throw an error. Since these methods do not throw an error, try...catch will not work. Ensure you understand the difference.
