CFD Online Discussion Forums - Sample not working correctly

Hi
I am trying to compare velocity profile data from two meshes. My geometry is two pipes connected at 90 degrees to each other via a mitered sharp bend. My sampleDict below, I am getting error given below sample dict. Can someone possible identify the reason for the error. I have tried to remove surface part as well as I only want to have velocity vector values on the sample lines drawn in folder sets. I shall be very grateful for support.

Regards
