XDataProperty causes Swagger to fail

BIZ TMS XData

I have the following entity in my XData-Server:

type
  [Entity]
  [Table('test')]
  [Id('fid', TIdGenerator.IdentityOrSequence)]
  TkdbTest = class
  private
    [Column('caption', [])]
    Fcaption: string;
    Fspecial: Integer;
    [Column('id', [TColumnProp.Required, TColumnProp.NoInsert, TColumnProp.NoUpdate])]
    Fid: Integer;
  public
    property caption: string read Fcaption write Fcaption;
    [XDataProperty]
    property special: Integer read Fspecial write Fspecial;
    property id: Integer read Fid write Fid;
  published
  end;

With the [XDataProperty] attribute calling swaggerui fails. Without it works (but of course without the special property). Calling this url http://127.0.0.1:2001/v1/swaggerui#/ I get this error:

Fetch error
Internal Server Error http://127.0.0.1:2001/kdb/v1/openapi/swagger.json

Do I miss something or is this a bug?
Kind regards
Harald

You should debug your application to properly see what is the real error being raised by the server.
