Cannot sweep multiple curve path & object

Dear all,

My question is related to the Sweep 1 component in grasshopper.

I have series of curves that merge to a line to form a tensile like structure.
At the bottom of this line, I have an objects(curve) that I would like to loft along each line.

My issue is when I try to use Swp1, there is an error. is it because there is an invalid curve in the list of lines? If so how do I limit the number of items that are fed to the swp1. If that’s not an issue, what can I do to fix it? Putting the path and the object through list item to get individual items seem to work.

I hope I was as clear as I could have been.
Any help would be greatly appreciated. Thank you in advance.

Kind regards,
