This typically occurs when the metadata definition of the OData service does not align with the actual data model or when there are issues with the configuration of the service.

  Incorrect Annotations: The advertising properties (like @odata.type, @odata.navigation, etc.) may not be correctly defined for the complex type in question.
  Model Changes: If there have been recent changes to the underlying data model (like adding or removing fields), the OData service may not have been updated accordingly.
