Most of the fields on the Player Resource objects in Dota are indexed by a value called player ID, which is between 0-9 inclusive for players on Radiant or Dire, and 10-31 for spectators and broadcasters. Some of the fields have a size of 10, and some 32.

Your value for player is 133, which isn't a player id, or even a player/client entity index. It may be another entity, such as a hero. You can get a player's id by looking at the m_iPlayerID sendprop on the player.
