Again problem ...
I'm trying parse such result: https://api.exmo.com/v1/pair_settings/

function Get_Pair_Settings return Pair_Settings_Vector_Package.Vector is
      JSON    : Unbounded_String :=3D Null_Unbounded_String;
      URL_Str : Unbounded_String :=3D To_Unbounded_String("https://api.exmo=
.com/v1/pair_settings/");
     =20
      Current_JSON_Item, JSON_Main_Node : JSON_Value :=3D Create;
      JSON_Result_Array : JSON_Array :=3D Empty_Array;=20
     =20
      Result  : Pair_Settings_Vector_Package.Vector;
   begin
      JSON :=3D To_Unbounded_String(Message_Body(Get(URL =3D> To_String(URL=
_Str))));
      JSON_Main_Node :=3D Read(JSON);             =20
      JSON_Result_Array :=3D Get(JSON_Main_Node);
=20
      if Length(JSON_Result_Array) > 0 then
         for i in 1 .. Length(JSON_Result_Array) loop
            Put_Line("123");
         end loop;
      end if;
     =20
      return Result;
     =20
   end;

...

raised CONSTRAINT_ERROR : gnatcoll-json.adb:1328 discriminant check failed
