Paraview Surface LIC not working

Hello, I have simulated a simple flow over a 2D bluff body using SU2, saved my results in vtu format and I want to visualise the streamlines.
I’ve loaded Surface LIC from the plug-ins and when I use stream tracer I can select the representation by Surface LIC, however it shows nothing, I just get an empty screen.
I’ve also attached the vtu file for reference.
Any help would be greatly appreciated, thanks in advance.

SurfaceLIC is for surfaces, not lines.
