Screeps getDirectionTo returning -2

var enemy_creep = creep.pos.findNearest(Game.HOSTILE_CREEPS);

if (enemy_creep) 
    var enemy_direction = creep.pos.getDirectionTo(enemy_creep);

I'm trying to do something like this in screeps but this function just keeps returning -2. I don't see any mention in the documentation of this error code. I've also tried the other version of the function using the x and y position of the enemy creep with the same result.

I think -2 is the error code for no path found, based on the game constants (below notify) So what ch4rlyp is saying might be correct, although the game docs are not saying anything about it needing to be near. Perhaps it's a bug?

Game.ERR_NO_PATH -2

We can know the direction of a enemy but only if it's near your own creep, works fine with findInRange(Game.HOSTILE_CREEPS, 1).

var enemy_creep = creep.pos.findInRange(Game.HOSTILE_CREEPS, 1)[0];

if (enemy_creep) {
    var enemy_direction = creep.pos.getDirectionTo(enemy_creep);
}
