Successfully installed the OUI plugin but the following error keeps occuring within the logstash log:

This causes the logstash pipeline to close then restart, though some OUI data is making to my elastic search instance. The MACs i'm sending are all fine too.
anybody got any ideas?
Thanks in advance
