What to do if MeshAgentPath.corners gives wrong coordinates?

Question

Unity

I need to get the necessary points passing through the terrain, I get them like this

Vector3[] MeshCorners = new Vector3[]{};
MeshAgentPath = new NavMeshPath();
NavMesh.CalculatePath(TargetA.transform.position, TargetB.transform.position, NavMesh.AllAreas, MeshAgentPath);
if(MeshAgentPath.status == NavMeshPathStatus.PathComplete){
  MeshCorners = MeshAgentPath.corners;

It often gives out normal coordinates, but sometimes it’s generally crazy, for example, it must move in a straight line, but the coordinates are lined up so that it moves straight then down somewhere, then again to the previous position and then further, or not straight, but obliquely forward down and also obliquely up , although it was possible directly ... I

already set up the agent, voxels, tiles, but still nothing ...
I think maybe I'm calculating incorrectly in the code, maybe there are some pitfalls?
