Error statement: unable to solve path


I sometimes get this error statement and I dont know how to solve it. Can somebody help? Is it because of the Resource Frame I put in.

That error means the target walking destination for the human is inside an obstacle. You can click ShowObstacles in the transport controller to visualize your obstacle components.
You could add any problematic areas to precision obstacles or to exclude those components if needed.
