> When using the ControlRate processor, defining the "Grouping Attribute" with a missing/non-existing attribute name produces NullPointerException errors.
> Processor configuration:
> {quote}
> Rate Control Criteria: flowfile count
> Maximum rate: 10
> Rate Controlled Attributes: (No value set)
> Time Duration: 1 min
> Grouping Attribute: foobar
> {quote}
> ControlRate with the following configuration when sent a flowfile without the attribute {{foobar}} generates the following error:
> bq. ControlRate\[id=dff05b32-015f-1000-db55-5957a9298bab] ControlRate\[id=dff05b32-015f-1000-db55-5957a9298bab] failed to process due to java.lang.NullPointerException; rolling back session: null
> Additionally, the incoming flowfiles now ends up in some "dead" state where I'm unable to even empty the queue.
> A simple template for reproduction is attached.
