Try providing current position as target.pos instead of { pos: target.pos, range: 1 }. I might be wrong but according to docs it seems only destination accepts object like that. Primary position is simple position object.

Yes, I am new to this game but I do have some years spent developing and designing various projects and tools. In business people often forget or cannot afford to think about optimization too much.

It is coding competition after all
