> h3. Problem analisys
> The error happens bacause of [NIFI-9491.|https://github.com/apache/nifi/commit/7c6bdcb035094db521b3007e1ccd298052cbfddd]
> The missing dependency included in the pom.xml ([https://github.com/apache/nifi/blob/main/nifi-nar-bundles/nifi-ranger-bundle/nifi-ranger-resources/pom.xml#L58)] however during assembly, the jar is not copied under ext/ranger/install/lib/ directory.
> The reason behind is probably, because the lib has provided scope:
> {code:java}
> [INFO] --- maven-dependency-plugin:3.1.2:tree (default-cli) @ nifi-ranger-plugin ---
> [INFO] org.apache.nifi:nifi-ranger-plugin:jar:1.16.0-SNAPSHOT
> [INFO] \- org.slf4j:jcl-over-slf4j:jar:1.7.32:provided {code}
> h3. Workaround
> copy the jcl-over-slf4j lib to ext/ranger/install/lib/ directory.
