Hi,Upon checking some behaviours in NiFi with Tamas Palfy, we have found that function signatures like this can be a frequent source of error:
|public FlowFile penalize(FlowFile flowFile) { ... }| I documented the issue here: https://cloudera.atlassian.net/wiki/spaces/ENG/pages/610534373/Discarding+Return+Values+in+NiFiIt would be nice if a Java dev with some spare time could look more into the issue and share their findings.
Cheers, Adam
