Train of scv takes no effect

[MrVermond]

Hi Matthias,

can you help me out, im trying to get application to train a scv but it just will not work
Here is my code

static Action BuildScv(GameState state)
        {
            var unit = state.NewObservation.Observation.RawData.Units.First(u => u.UnitType == (uint)18);
           

            var a5 = new Action();
            a5.ActionRaw = new ActionRaw();
            a5.ActionRaw.UnitCommand = new ActionRawUnitCommand();
                 
            a5.ActionRaw.UnitCommand.AbilityId = (int)524;
            a5.ActionRaw.UnitCommand.TargetUnitTag = unit.Tag;
            a5.ActionRaw.UnitCommand.UnitTags.Add(unit.Tag);
            return a5;
        }

sadly the api does not return any error.

BR and thanks in advance
Nick
