[OPNFLWPLUG-973] Errors trying to create OpenFlow flows with Nicira NSH extensions after Yangtools 2.0.1 version bump

Mon, 22 Jan 2018 21:25:41 +0000

After the Yangtools 2.0.1 version bump, its no longer possible to programatically create SFC OpenFlow flows. I get the following errors in the karaf.log: https://pastebin.com/RvzktbLi

The rest of the flows that dont have any Nicira NSH extensions are written successfully.

The problematic flows dont get written to the Config data store, so I cant dump that to show them. What I was able to do was to log the flows. These are the problematic flows from karaf.log:
