worldTolocal position while rotating parent object

[RAUMIK_RANA]

I got incorrect worldTolocal value if parent object is rotated at angle.
Here is related code for that.

first, I create one object3d and add it to scene.
after that I moved that object to required position at ‘pos’
and set z rotation to ‘rot.z’
after that updateMatrixWorld().

now I have array of xyPos from which I want to cast ray.

everything works fine when I set z rotation to 0.
but if I changed rotation I got incorrect worldTolocal position.

I also attached console screenshot for both.

function createHolesB(xyPos, pos, rot) {

var mainObj = new THREE.Object3D()
    mainObj.name = "mainPattern_" + mainPatternGrp
    mainPatternGrp++
    scene.add(mainObj)
    mainObj.position.copy(pos)
    mainObj.rotation.z = rot.z
    // console.log(mainObj.rotation);
    mainObj.updateMatrixWorld()



    xyPos.forEach((e, i) => {
        // debugger
        var raycaster = new THREE.Raycaster();
        console.log(scene.getObjectByName("mainPattern_0").position);
        debugger
        var castPo = mainObj.worldToLocal(new THREE.Vector3(e.x, e.y, 1000))

        console.log(scene.getObjectByName("mainPattern_0").position);

        castPo.negate()
        castPo.z = 1000
        console.log(castPo);
        raycaster.set(castPo, new THREE.Vector3(0, 0, -1))

        var intersection = raycaster.intersectObjects(addedObject, true);
        console.log(intersection);

        debugger
