C# Invalid Points Assigned to 2D Edge Collider

I had this code working a moment ago and now I'm getting warnings saying that I've assigned invalid points to my 2D Edge Collider. I've tried checking if(keyVertices.Length > 0), if(keyVertices != null) and if(v != null) but none of them resolved this issue. I'm honestly not sure where this error is coming from.
