navmesh.findpath always return null

Hi guys! i’m trying to implement pathfinding in my game by using navmesh

but no matter what coordinates i pass it always returns null
i build navmesh in Tiled
there is a code:
const objectLayer = this.tilemap.getObjectLayer(“navmesh”);
console.log(objectLayer)
const navMesh = this.navMeshPlugin.buildMeshFromTiled(“mesh”, objectLayer, 5);
console.log(navMesh);
const path = navMesh.findPath({ x:1500, y: 2500 }, { x: 1600, y: 2600 });
console.log(path);

this is game

if i add methods for visually debugging navmesh it becomes like this
