This typically occurs during the definition of OData services when there are duplicate property names in the same complex type.

  Check for Inheritance: If your complex type is inheriting from another type, ensure that the parent type does not have a property with the same name.
  Use Unique Names: Ensure that all property names within a complex type are unique to avoid conflicts.
