Having had the thread checked the format looks OK. Can you check if "Point-Direction" and "point-direction" makes a difference? Are there any spaces or odd characters in the path name? Did you type the commands into a text editor or copy from the documentation? If the latter can you check for white space characters.
The two points defined create a cylinder that is projected to the two surfaces (injection & extraction), I assume the axis this sets will hit those surfaces? That shouldn't be the issue here given the error seems to be earlier in the set up.
