NiFi InvokeHTTP Post Fails Silently


NiFi InvokeHTTP Post Fails Silently

New Contributor



I am new to NiFi and am trying to setup an InvokeHTTP processor to get a bearer token from an API. I can get the token using cURL on the same server as NiFi is installed on but I cannot get it to work in NiFi.
