What is ‘ ObjectDoesNotExist’ ?

It is triggered when a query, intended to retrieve a single object using the get() method, fails to locate any records that match the specified criteria. This exception serves as a mechanism for handling scenarios where the developer anticipates the existence of a single object but must gracefully manage situations where it is not found.
