I came across this error while attempting to extrude a polygon between two TINs. My issue was that my polygon had too many vertices (I drew it with the free hand tool). I used Simplify Polygon to make it have fewer vertices and the tool ran. Not sure if that will help in this scenario, but was a similar issue I think.
