Could it be the cause?   ERROR [main] org.apache.nifi.NiFi Failure to launch NiFi due to java.util.ServiceConfigurationError: org.apache.nifi.processor.Processor: Provider org.apache.nifi.processors.standard.AttributesToJSON could not be instantiated java.util.ServiceConfigurationError: org.apache.nifi.processor.Processor: Provider org.apache.nifi.processors.standard.AttributesToJSON could not be instantiated at java.util.ServiceLoader.fail(ServiceLoader.java:232) at java.util.ServiceLoader.access$100(ServiceLoader.java:185) at java.util.ServiceLoader$LazyIterator.nextService(ServiceLoader.java:384) at java.util.ServiceLoader$LazyIterator.next(ServiceLoader.java:404) at java.util.ServiceLoader$1.next(ServiceLoader.java:480) at org.apache.nifi.nar.ExtensionManager.loadExtensions(ExtensionManager.java:142) at org.apache.nifi.nar.ExtensionManager.discoverExtensions(ExtensionManager.java:117) at org.apache.nifi.web.server.JettyServer.start(JettyServer.java:702) at org.apache.nifi.NiFi.<init>(NiFi.java:160) at org.apache.nifi.NiFi.main(NiFi.java:268) Caused by: java.lang.NoSuchMethodError: com.fasterxml.jackson.core.JsonFactory.requiresPropertyOrdering()Z at com.fasterxml.jackson.databind.ObjectMapper.<init>(ObjectMapper.java:530) at com.fasterxml.jackson.databind.ObjectMapper.<init>(ObjectMapper.java:449) at org.apache.nifi.processors.standard.AttributesToJSON.<clinit>(AttributesToJSON.java:132) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at java.lang.Class.newInstance(Class.java:442) at java.util.ServiceLoader$LazyIterator.nextService(ServiceLoader.java:380) ... 7 common frames omitted ...
