"Could not find point 0: -101.5051900 32.2082800 within a radius of 350.0 meters.; Could not find point 1: -101.5036500 32.2128400 within a radius of 350.0 meters."
ors searches by default only in a 350 m radius around the points. If there are no points on the used street network in that circle it won’t accept this point, hence the error.
You need to choose your points closer to the streets or use the radiuses parameter to increase the search radius.
