Hi, I'm part of the maker community, and I'm trying to connect RsEmulate with Node-RED and create a SCADA system using Ignition. I'm trying to install the Node-RED module, but although the license is activated, the **status** shows **FAULTED**. I've already uninstalled both Ignition and Node-RED, but I keep getting the same problem. If anyone could help me, I would be very thankful! `java.lang.Exception: Exception while starting up module "org.imdc.nodered.IgnitionNodeRED". at com.inductiveautomation.ignition.gateway.modules.ModuleManagerImpl$LoadedModule.startup(ModuleManagerImpl.java:2452) at com.inductiveautomation.ignition.gateway.modules.ModuleManagerImpl.startup(ModuleManagerImpl.java:423) at com.inductiveautomation.ignition.gateway.IgnitionGateway.startupInternal(IgnitionGateway.java:1334) at com.inductiveautomation.ignition.gateway.redundancy.RedundancyManagerImpl.startup(RedundancyManagerImpl.java:307) at com.inductiveautomation.ignition.gateway.IgnitionGateway.initRedundancy(IgnitionGateway.java:777) at com.inductiveautomation.ignition.gateway.IgnitionGateway.lambda$initInternal$1(IgnitionGateway.java:700) at com.inductiveautomation.ignition.common.execution.impl.BasicExecutionEngine$ThrowableCatchingRunnable.run(BasicExecutionEngine.java:550) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.base/java.util.concurrent.FutureTask.run(Unknown Source) at java.base/java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(Unknown Source) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.base/java.lang.Thread.run(Unknown Source) Caused by: java.lang.NoClassDefFoundError: org/eclipse/jetty/websocket/server/JettyWebSocketServlet at java.base/java.lang.ClassLoader.defineClass1(Native Method) at java.base/java.lang.ClassLoader.defineClass(Unknown Source) at java.base/java.security.SecureClassLoader.defineClass(Unknown Source) at java.base/java.net.URLClassLoader.defineClass(Unknown Source) at java.base/java.net.URLClassLoader$1.run(Unknown Source) at java.base/java.net.URLClassLoader$1.run(Unknown Source) at java.base/java.security.AccessController.doPrivileged(Unknown Source) at java.base/java.net.URLClassLoader.findClass(Unknown Source) at com.inductiveautomation.ignition.gateway.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:37) at java.base/java.lang.ClassLoader.loadClass(Unknown Source) at com.inductiveautomation.ignition.gateway.modules.ModuleClassLoader.loadClass(ModuleClassLoader.java:85) at java.base/java.lang.ClassLoader.loadClass(Unknown Source) at org.imdc.nodered.GatewayHook.startup(GatewayHook.java:39) at com.inductiveautomation.ignition.gateway.modules.ModuleManagerImpl$LoadedModule.startup(ModuleManagerImpl.java:2446) ... 12 more Caused by: java.lang.ClassNotFoundException: org.eclipse.jetty.websocket.server.JettyWebSocketServlet at java.base/java.net.URLClassLoader.findClass(Unknown Source) at com.inductiveautomation.ignition.gateway.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:37) at java.base/java.lang.ClassLoader.loadClass(Unknown Source) at com.inductiveautomation.ignition.gateway.modules.ModuleClassLoader.loadClass(ModuleClassLoader.java:85) at java.base/java.lang.ClassLoader.loadClass(Unknown Source) ... 26 more 8.1.49 (b2025081208) Azul Systems, Inc. 17.0.15` ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/3/f/3f026cfa5ab8c46eda0f0ba3bc7fcbb8d4cd8ef8.png) ---

We upgrade to Jetty v12 in 8.1.49; I bet the Node Red module needs to be updated and a new version released as well. ---

I think it would be. Best would be to file an issue with this stack trace on the Node Red module repository and then also ask the maintainers while you’re at it. > **[GitHub - IgnitionModuleDevelopmentCommunity/IgnitionNode-RED: Adds support for Node-RED](https://github.com/IgnitionModuleDevelopmentCommunity/IgnitionNode-RED)** > > Adds support for Node-RED ---

Alright, I’ll open an issue on the Node-RED module repository. In the meantime, I might try downgrading to 8.1.48 so I can continue my tests until the module is updated. Thanks ---

I can help take a look at this when I get some free time. I helped upgrade it for Jetty 10 w/ 8.1.25–should be pretty straightforward.
