NiFi-Kylo feed error (Ingest Feed? processor error)

NiFi-Kylo feed error (Ingest Feed? processor error)

New Contributor

I had setup kylo software on HDP edge node and connected it to an external HDF (NiFi) cluster.

I had ingested an template (Advance ingest) and created a feed from kylo using it.


At a certain step in NiFi the processor (processor name → Ingest Feed?) gives an error as below.

I am not sure how to figure out and fix the cause.
