Specifically, it means that the EDM (Entity Data Model) type for a property has changed, which can lead to inconsistencies in the data model.
  Cause:
  This error typically occurs due to one of the following reasons:
  
  Model Changes: Changes made to the data model, such as altering the data type of a property in the entity definition.
  Inconsistent Metadata: The metadata in the service definition does not match the underlying data model or database schema.

  Clear Cache: Sometimes, cached metadata can cause issues. Clear the cache for the service or the application to ensure that the latest definitions are being used.
  
  
  Check for Dependencies: Ensure that any dependent objects (like other entities, views, or services) are also updated to reflect the changes made to the entity type.
  
  
  Transport Changes: If the changes were made in a development environment, ensure that they are properly transported to the quality or production environment.
