Igor, Seems perfectly reasonable. If the path is not found, an empty value will result. You can control in the processor properties as to whether or not this is a warn worthy event or if it should be ignored; the configuration you would likely desire in this case.
Let us know if this does not work out as anticipated. On Mon, Aug 8, 2016 at 2:47 PM, Igor Kravzov <igork.ine...@gmail.com> wrote: > Hi, > > In my workflow I need to identify retweets.
