I'm trying to build a container and retrieve the id of the construction site.

The constructing part works fine, i get an OK as result and see the site on the map.

However, retrieving it directly after the Construction Line fails with different kind of approaches.

With all the tests, i don't see the container. If I wait however one tick, it starts to appear. Why is that and is there any way to retrieve the id directly after creating it?

    testBuildContainer: function(room){
        var result = room.createConstructionSite(10,10, STRUCTURE_CONTAINER);
        console.log("result: " + result);
        
        // Test 1
        var room_find_c = room.find(FIND_CONSTRUCTION_SITES);
        console.log(JSON.stringify(room_find_c, null, 4));
        
        var room_find_s = room.find(FIND_STRUCTURES);
        console.log(JSON.stringify(room_find_s, null, 4));
        
        // Test 2
        var room_lookat = room.lookAt(10,10);
        console.log(JSON.stringify(room_lookat, null, 4));

        // Test 3
        console.log(JSON.stringify(room.find(FIND_CONSTRUCTION_SITES,{filter: (i)=> {return i.structureType==STRUCTURE_CONTAINER}}), null,4));
        
        // Test 4
        console.log(JSON.stringify(room.find(FIND_STRUCTURES,{filter: (i)=> {return i.structureType==STRUCTURE_CONTAINER}}), null,4));
    }
