Use Screenshots if accurate.\n\nFor new features, show how the feature would be used.\n--\u003e\n\n1. Create a VM, say testvm.\n2. Create a network offering for Shared network with specifyVlan = false and no services ; enable the network offering.\n3. Create a shared network using this offering and provide only IPv4 gateway and netmask (no IP range provided).\nEx: `create network acltype=domain name=test-shared-network displaytext=test-shared-network networkofferingid=3dc6968e-6503-4fa3-8a38-09da72d7a846 gateway=1.1.1.1 netmask=255.255.255.0 physicalnetworkid=7691b1b8-2438-4843-9802-cb7f458d7757 zoneid=5b53d47b-d56a-4e6d-927c-3b61a58edf9f`\n4. Stop the VM testvm and attach network created (addNicToVirtualMachine) in step3, to the VM.\n5. Start the VM - this will fail.\n6. Remove the network (removeNicFromVirtualMachine) in step3, from the VM. Now, start the VM.\n7. Delete the network created in step 3 - It fails with below exception. \n\n```\n2025-01-24 05:00:13,653 ERROR [c.c.a.ApiAsyncJobDispatcher] (API-Job-Executor-37:ctx-c898771c job-126) (logid:65c35a14) Unexpected exception while executing org.apache.cloudstack.api.command.user.network.DeleteNetworkCmd\njava.lang.NullPointerException\n        at com.cloud.network.Networks$BroadcastDomainType.getSchemeValue(Networks.java:178)\n        at com.cloud.network.Networks$BroadcastDomainType.getValue(Networks.java:232)\n        at org.apache.cloudstack.engine.orchestration.NetworkOrchestrator.deleteVlansInNetwork(NetworkOrchestrator.java:3452)\n        at org.apache.cloudstack.engine.orchestration.NetworkOrchestrator$13.doInTransaction(NetworkOrchestrator.java:3352)\n        at org.apache.cloudstack.engine.orchestration.NetworkOrchestrator$13.doInTransaction(NetworkOrchestrator.java:3344)\n        at com.cloud.utils.db.Transaction$2.doInTransaction(Transaction.java:50)\n        at com.cloud.utils.db.Transaction.execute(Transaction.java:40)\n        at com.cloud.utils.db.Transaction.execute(Transaction.java:47)\n        at org.apache.cloudstack.engine.orchestration.NetworkOrchestrator.destroyNetwork(NetworkOrchestrator.java:3344)\n        at com.cloud.network.NetworkServiceImpl.deleteNetwork(NetworkServiceImpl.java:2695)\n        at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method)\n        at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)\n        at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)\n        at java.base/java.lang.reflect.Method.invoke(Method.java:566)\n        at org.springframework.aop.support.AopUtils.invokeJoinpointUsingReflection(AopUtils.java:344)\n        at org.springframework.aop.framework.ReflectiveMethodInvocation.invokeJoinpoint(ReflectiveMethodInvocation.java:198)\n        at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:163)\n        at org.apache.cloudstack.network.contrail.management.EventUtils$EventInterceptor.invoke(EventUtils.java:107)\n        at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:175)\n        at com.cloud.event.ActionEventInterceptor.invoke(ActionEventInterceptor.java:52)\n        at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:175)\n        at org.springframework.aop.interceptor.ExposeInvocationInterceptor.invoke(ExposeInvocationInterceptor.java:97)\n        at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:186)\n        at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:215)\n        at com.sun.proxy.$Proxy168.deleteNetwork(Unknown Source)\n        at org.apache.cloudstack.api.command.user.network.DeleteNetworkCmd.execute(DeleteNetworkCmd.java:72)\n        at com.cloud.api.ApiDispatcher.dispatch(ApiDispatcher.java:172)\n        at com.cloud.api.ApiAsyncJobDispatcher.runJob(ApiAsyncJobDispatcher.java:112)\n        at org.apache.cloudstack.framework.jobs.impl.AsyncJobManagerImpl$5.runInContext(AsyncJobManagerImpl.java:654)\n\n```\n\n8.
