What error can be avoided by adding objects to an application before fields?

Adding objects to an application before fields prevents the scenario where the object associated with a field is not found. When fields are created in an application, they often reference specific objects. If the objects are not defined first, the application may not be able to locate them when it tries to render or interact with the fields. This can lead to errors or the application malfunctioning since the field expects an associated object that is unavailable.

By establishing the objects first, you ensure that all fields have the necessary references, allowing the application to function properly without encountering missing object errors, ensuring smooth data handling and user interactions. This sequence of adding objects helps maintain the integrity and structure of the application, preventing runtime issues related to object accessibility.
