Strange survival mode only error

if(creep === Game.creeps["Worker0"])
{
    var sources = creep.pos.findClosest(Game.SOURCES);
    creep.moveTo(24,29);
    creep.harvest(sources);
    creep.transferEnergy(Game.creeps["Transport0"]);
}
if(creep === Game.creeps["Worker1"])
{
    var sources = creep.pos.findClosest(Game.SOURCES);
    creep.moveTo(25,29);
    creep.harvest(sources);
    creep.transferEnergy(Game.creeps["Transport0"]);
}

I get below error:

TypeError: Cannot read property 'forEach' of undefined
    at RoomPosition.findClosest (/opt/engine/dist/game/rooms.js:843:23)
    at module.exports (harvester:7:30)
    at main:24:11

It is weird because it works just fine in simulation mode but not in survival.

Solution

  • The Screeps API has been changed yesterday: changelog.

    You have to use findClosest(FIND_SOURCES) now instead of findClosest(Game.SOURCES).
