Describe the bug
A clear and concise description of what the bug is.
As we supported direction in path concat in #3920, a bug may occur if the ResultOpt in path is specified as EndV. This is because, in this case, only the end point of the path will be preserved, and if we concat the path by the start point, it will fail.
Fix it.
