Error unable to find path

MieskeB

I have created a small script. After some trying I cannot find where my mistake is... I keep getting error no path found (creep.moveto() returns -2). Here is my code:

var roleHarvester = {

/** @param {Creep} creep **/
run: function(creep) {
    if(creep.carry.energy < creep.carryCapacity) {
        
        var source = creep.room.find(FIND_SOURCES)[1];
        
        if(creep.harvest(source) == ERR_NOT_IN_RANGE) {
            console.log('x: ' + source.pos.x);
            console.log('y: ' + source.pos.y);
            
            if (creep.moveTo(source) == -2) {
                console.log('Cannot find path');
            }
        }
    }
    else {
        if(creep.transfer(Game.spawns['Spawn1'], RESOURCE_ENERGY) == ERR_NOT_IN_RANGE) {
            creep.moveTo(Game.spawns['Spawn1']);
        }
    }
}
};

module.exports = roleHarvester;

It shows in the log:

x: 11
y: 30
Cannot find path

The x and y value are the correct values of the source.

Why can't it find it's path?

same issue that have been reported here i guess: https://screeps.com/forum/topic/2257/creep-moveto-almost-always-returning-2

Basically the terrain is "wall" where it should not be. Seen a lot of people reporting this.
