Hi Everyone, I'm unable to start our keycloak server and could some assistance. Just to give a quick recap of background and steps we've taken.. We've been using keycloak 1.8.0 for a while and are in the process of migrating to a 2.2.1 instance in AWS. We're running standalone HA mode with two nodes behind a public ELB. I have configured JDBC Ping to save session state across both nodes in preproduction and it works there. I have configured production the same way as preprod (we're also using Chef so I know its configured the same). In production, we've taken a backup of the keycloak postgresql DB (1.8.0) and restored it to the keycloak DB our 2.2.1 instance is pointed to. I have set migrationStrategy to manual and it produced a .sql file to run. We had some issues running it related to indicies and tables and such already existing so we decided to run each statement line by line. This got us past the "Database not up-to-date" error, but we're now seeing this in the server.log which causes the startup to fail. Does anyone have an idea what the problem could be? 2017-02-07 17:16:50,380 ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool -- 55) MSC000001: Failed to start service jboss.undertow.deployment.default-server.default-host./auth: org.jboss.msc.service.StartException in service jboss.undertow.deployment. default-server.default-host./auth: java.lang.RuntimeException: RESTEASY003325: Failed to construct public org.keycloak.services. resources.KeycloakApplication(javax.servlet.ServletContext, org.jboss.resteasy.core.Dispatcher) at org.wildfly.extension.undertow.deployment.UndertowDeploymentService$1. run(UndertowDeploymentService.java:85) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker( ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run( ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) at org.jboss.threads.JBossThread.run(JBossThread.java:320) Caused by: java.lang.RuntimeException: RESTEASY003325: Failed to construct public org.keycloak.services.resources.KeycloakApplication( javax.servlet.ServletContext,org.jboss.resteasy.core.Dispatcher) at org.jboss.resteasy.core.ConstructorInjectorImpl.construct( ConstructorInjectorImpl.java:162) at org.jboss.resteasy.spi.ResteasyProviderFactory.createProviderInstance( ResteasyProviderFactory.java:2209) at org.jboss.resteasy.spi.ResteasyDeployment.createApplication( ResteasyDeployment.java:299) at org.jboss.resteasy.spi.ResteasyDeployment.start( ResteasyDeployment.java:240) at org.jboss.resteasy.plugins.server.servlet.ServletContainerDispatcher. init(ServletContainerDispatcher.java:113) at org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.init( HttpServletDispatcher.java:36) at io.undertow.servlet.core.LifecyleInterceptorInvocation.proceed( LifecyleInterceptorInvocation.java:117) at org.wildfly.extension.undertow.security.RunAsLifecycleInterceptor.init( RunAsLifecycleInterceptor.java:78) at io.undertow.servlet.core.LifecyleInterceptorInvocation.proceed( LifecyleInterceptorInvocation.java:103) at io.undertow.servlet.core.ManagedServlet$DefaultInstanceStrategy.start( ManagedServlet.java:231) at io.undertow.servlet.core.ManagedServlet.createServlet( ManagedServlet.java:132) at io.undertow.servlet.core.DeploymentManagerImpl.start( DeploymentManagerImpl.java:526) at org.wildfly.extension.undertow.deployment.UndertowDeploymentService. startContext(UndertowDeploymentService.java:101) at org.wildfly.extension.undertow.deployment.UndertowDeploymentService$1. run(UndertowDeploymentService.java:82) ... 6 more Caused by: javax.persistence.EntityNotFoundException: Unable to find org.keycloak.models.jpa.entities.ClientEntity with id asdfg123-123x-123e-1xx1-sdkasdjf7123 at org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImp l$JpaEntityNotFoundDelegate.handleEntityNotFound( EntityManagerFactoryBuilderImpl.java:144) at org.hibernate.proxy.AbstractLazyInitializer.checkTargetState( AbstractLazyInitializer.java:242) at org.hibernate.proxy.AbstractLazyInitializer.initialize( AbstractLazyInitializer.java:159) at org.hibernate.proxy.AbstractLazyInitializer.getImplementation( AbstractLazyInitializer.java:266) at org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer.invoke( JavassistLazyInitializer.java:68) at org.keycloak.models.jpa.entities.ClientEntity_$$_jvst1c4_8.getRealm( ClientEntity_$$_jvst1c4_8.java) at org.keycloak.models.jpa.RealmAdapter.getMasterAdminClient( RealmAdapter.java:1234) at org.keycloak.models.cache.infinispan.entities.CachedRealm.<init>( CachedRealm.java:241) at org.keycloak.models.cache.infinispan.RealmCacheSession. getRealm(RealmCacheSession.java:379) at org.keycloak.migration.migrators.MigrateTo1_9_0. migrate(MigrateTo1_9_0.java:45) at org.keycloak.migration.MigrationModelManager.migrate( MigrationModelManager.java:74) at org.keycloak.services.resources.KeycloakApplication.migrateModel( KeycloakApplication.java:221) at org.keycloak.services.resources.KeycloakApplication.migrateAndBootstrap( KeycloakApplication.java:162) at org.keycloak.services.resources.KeycloakApplication$ 1.run(KeycloakApplication.java:121) at org.keycloak.models.utils.KeycloakModelUtils.runJobInTransaction( KeycloakModelUtils.java:295) at org.keycloak.services.resources.KeycloakApplication. <init>(KeycloakApplication.java:112) 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 org.jboss.resteasy.core.ConstructorInjectorImpl.construct( ConstructorInjectorImpl.java:150) ... 19 more
