The way you try to do it does not conform with the documentation.
ListVectorPlot3D expect either
1. a rectangular array of height values
2. A list. The element of the list are TWO lists, in which the first is
point and the second is the vector (of the field) at that point

so, unless you meet with one of the requirements you cannot do it
