It seems that you are trying to load a new (1.9.2) processor into a rather old version of Nifi (1.2).

In general I would not expect that to succeed.


A quick glance suggests that the websocket processers have been introduced since 1.5, so I don't think there is a 1.2 version for this.


Please consider using a more recent version of Nifi as you are currently 7 versions behind.
