Hi Matt, I will try with different implementations of Provenanve repo, unit now I used default one: org.apache.nifi.provenance.MiNiFiPersistentProvenanceRepository.
Regarding C2 server, I downloaded version 0.5.0 here: https://nifi.apache.org/minifi/download.html , at the bottom of the page. Where can I download 1.14.0 version?

If not the VolatileProvenanceRepository, can you try that as a workaround? Also are you using the 1.14.0 version of the C2 server?
