> Evaluating some work for UpdateAttributes, specifically the ability to delete attributes, led to being able to delete UUID (https://github.com/apache/nifi/pull/116)
> As a result, the framework was nonplussed at the missing core attribute, uuid:
> {quote}
> 12:53:35 ESTERROR6d65c083-eb22-4ae7-b542-de808b1402d0
> UpdateAttribute[id=6d65c083-eb22-4ae7-b542-de808b1402d0] UpdateAttribute[id=6d65c083-eb22-4ae7-b542-de808b1402d0] failed to process session due to java.lang.IllegalStateException: Cannot create Provenance Event Record because FlowFile UUID is not set: java.lang.IllegalStateException: Cannot create Provenance Event Record because FlowFile UUID is not set
> {quote}
> Not sure if this applies to other core attributes, but at minimum, it seems like the UUID needs to have some framework level guarding against it from being inappropriately modified.
