Hello Experts, I have a custom processor where I have below lines of code -  private ReadContext configJsonCtx = JsonPath.parse(configJsonString);     private List<Object> workFlows = configJsonCtx.read("$.Workflow");       this.workFlows.forEach((workFlowObj) -> {     try {     DocumentContext workFlow = JsonPath.parse(workFlowObj);   ........     This is working fine with Nifi 16 and com.jayway.jsonpath.json-path:2.4.0 dependency. But now I am trying to upgrade to nifi 24 and I am getting below error when I do that Any idea what could be the reason and solution for the same.   2024-03-12 05:09:08,815 ERROR [Timer-Driven Process Thread-320] c.o.n.p.o.O9QueueRouting O9QueueRouting[id=8718e632-f033-372b-8f6c-682399fbf9b6] Exception: java.lang.ClassCastException: class java.util.LinkedHashMap cannot be cast to class com.jayway.jsonpath.DocumentContext (java.util.LinkedHashMap is in module java.base of loader 'bootstrap'; com.jayway.jsonpath.DocumentContext is in unnamed module of loader org.apache.nifi.nar.NarClassLoader @147e0734) java.lang.ClassCastException: class java.util.LinkedHashMap cannot be cast to class com.jayway.jsonpath.DocumentContext (java.util.LinkedHashMap is in module java.base of loader 'bootstrap'; com.jayway.jsonpath.DocumentContext is in unnamed module of loader org.apache.nifi.nar.NarClassLoader @147e0734) at com.o9solutions.nifi.processors.o9_custom_processors.O9QueueRouting.lambda$onScheduled$0(O9QueueRouting.java:299) at java.base/java.util.ArrayList.forEach(ArrayList.java:1541) at com.o9solutions.nifi.processors.o9_custom_processors.O9QueueRouting.onScheduled(O9QueueRouting.java:269) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at org.apache.nifi.util.ReflectionUtils.invokeMethodsWithAnnotations(ReflectionUtils.java:145) at org.apache.nifi.util.ReflectionUtils.invokeMethodsWithAnnotations(ReflectionUtils.java:133) at org.apache.nifi.util.ReflectionUtils.invokeMethodsWithAnnotations(ReflectionUtils.java:78) at org.apache.nifi.util.ReflectionUtils.invokeMethodsWithAnnotation(ReflectionUtils.java:55) at org.apache.nifi.controller.StandardProcessorNode.lambda$initiateStart$8(StandardProcessorNode.java:1765) at org.apache.nifi.engine.FlowEngine$3.call(FlowEngine.java:123) at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) at java.base/java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:304) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at java.base/java.lang.Thread.run(Thread.java:829) Thanks in advnace Mahendra ...
