Subject transfer relationship not specified

Hi All,

Wondering if someone could help me with a custom processor error. I'm
getting an error when doing a session commit in onTrigger [0].

The flow file logic is super simple. Get a whole bunch, either ignore them,
transfer them to a relationship or delete them. Most get deleted from the
session. Not quite sure what I'm missing here. Do I need to free the
FlowFiles somehow? Do I need to 'unget' the files I got from the session -
those that didn't get transferred or removed?

Thanks for your help!
