Remarks
The FindPathUpstreamTask object is a directional trace task. By default, network elements with indeterminate or uninitialized flow direction will not be traced.
If you do not specify weights for your trace task, the FindPathUpstreamTask will return the path with the fewest number of network elements.
If you do specify weights for your trace task, the FindPathUpstreamTask will treat network elements with negative weight values as having infinite cost.
