Hello. I am trying to determine a way to get the size of a NiFi flowfile within a Groovy script. Has anyone done this before, and can tell me how to do this from within Groovy?
This https://jameswing.net/nifi/nifi-internal-fields.html describes fileSize as a hidden field that can be accessed via expression language, but I do not see how I can reference that in a Groovy script. Thanks in advance for any help.
