webservice error: Request part has not been evaluated yet
2
Recently we've started to experience a strange behaviour when calling a consumed webservice of another Mendix application. The error occurs randomly, both in the cloud as locally. It appears that Mendix is temporarily unable to compile it's own XML message. This issue resolves itself after multiple tries (with the same request, so no changes in content), or after restarting the application. The error we recieve can nowhere be found on the internet. Does anyone have an idea what might be the cause? Mendix version: 5.13.1 This is the stacktrace: java.lang.IllegalArgumentException: Request part has not been evaluated yet. at com.google.common.base.Preconditions.checkArgument(Preconditions.java:92) at com.mendix.integration.webservices.call.messageparts.SimpleMessageRequestPart.writeContents(SimpleMessageRequestPart.java:56) at com.mendix.integration.webservices.call.messageparts.SimpleBodyPart.render(SimpleBodyPart.java:26) at com.mendix.integration.webservices.call.WebserviceCaller.buildSOAPRequestMessage(WebserviceCaller.java:494) at com.mendix.integration.webservices.call.WebserviceCaller.call(WebserviceCaller.java:126) at com.mendix.integration.webservices.WebserviceModule.callWebservice(WebserviceModule.java:202) at com.mendix.integration.internal.IntegrationImpl.callWebservice(InternalIntegrationImpl.scala:159) at com.mendix.integration.actions.microflow.CallWebServiceAction.execute(CallWebServiceAction.scala:71) at com.mendix.modules.microflowengine.microflow.impl.MicroflowObject.execute(MicroflowObject.java:49) at com.mendix.modules.microflowengine.microflow.impl.MicroflowImpl.executeAfterBreakingIfNecessary(MicroflowImpl.java:193) at com.mendix.modules.microflowengine.microflow.impl.MicroflowImpl.executeAction(MicroflowImpl.java:148) at com.mendix.systemwideinterfaces.core.UserAction.execute(UserAction.java:53) at com.mendix.core.actionmanagement.CoreAction.doCall(CoreAction.java:291) at com.mendix.core.actionmanagement.CoreAction.call(CoreAction.java:276) at com.mendix.core.actionmanagement.ActionManager$1.execute(ActionManager.java:204) at com.mendix.util.classloading.Runner.doRunUsingClassLoaderOf(Runner.java:37) at com.mendix.core.actionmanagement.ActionManager.executeSync(ActionManager.java:199) at com.mendix.core.component.InternalCore.executeSync(InternalCore.java:235) at com.mendix.modules.microflowengine.actions.SubMicroflowAction.execute(SubMicroflowAction.scala:33) at com.mendix.modules.microflowengine.microflow.impl.MicroflowObject.execute(MicroflowObject.java:49) at com.mendix.modules.microflowengine.microflow.impl.MicroflowImpl.executeAfterBreakingIfNecessary(MicroflowImpl.java:193) at com.mendix.modules.microflowengine.microflow.impl.MicroflowImpl.executeAction(MicroflowImpl.java:148) at com.mendix.systemwideinterfaces.core.UserAction.execute(UserAction.java:53) at com.mendix.core.actionmanagement.CoreAction.doCall(CoreAction.java:291) at com.mendix.core.actionmanagement.CoreAction.call(CoreAction.java:276) at com.mendix.core.actionmanagement.ActionManager$1.execute(ActionManager.java:204) at com.mendix.util.classloading.Runner.doRunUsingClassLoaderOf(Runner.java:37) at com.mendix.core.actionmanagement.ActionManager.executeSync(ActionManager.java:199) at com.mendix.core.component.InternalCore.executeSync(InternalCore.java:235) at com.mendix.modules.microflowengine.actions.SubMicroflowAction.execute(SubMicroflowAction.scala:33) at com.mendix.modules.microflowengine.microflow.impl.MicroflowObject.execute(MicroflowObject.java:49) at com.mendix.modules.microflowengine.microflow.impl.MicroflowImpl.executeAfterBreakingIfNecessary(MicroflowImpl.java:193) at com.mendix.modules.microflowengine.microflow.impl.MicroflowImpl.executeAction(MicroflowImpl.java:148) at com.mendix.systemwideinterfaces.core.UserAction.execute(UserAction.java:53) at com.mendix.core.actionmanagement.CoreAction.doCall(CoreAction.java:291) at com.mendix.core.actionmanagement.CoreAction.call(CoreAction.java:276) at com.mendix.core.actionmanagement.CustomActionMonitorImpl$$anonfun$run$1.apply(CustomMonitoredAction.scala:17) at com.mendix.core.session.Worker$$anonfun$receive$3$$anonfun$2$$anon$1.execute(ActionDispatching.scala:151) at com.mendix.util.classloading.Runner.doRunUsingClassLoaderOf(Runner.java:37) at com.mendix.core.session.Worker$$anonfun$receive$3$$anonfun$2.apply(ActionDispatching.scala:153) at scala.util.Try$.apply(Try.scala:191) at com.mendix.core.session.Worker$$anonfun$receive$3.applyOrElse(ActionDispatching.scala:147) at akka.actor.Actor$class.aroundReceive(Actor.scala:465) at com.mendix.core.session.Worker.aroundReceive(ActionDispatching.scala:140) at akka.actor.ActorCell.receiveMessage(ActorCell.scala:516) at akka.actor.ActorCell.invoke(ActorCell.scala:487) at akka.dispatch.Mailbox.processMailbox(Mailbox.scala:238) at akka.dispatch.Mailbox.run(Mailbox.scala:220) at akka.dispatch.ForkJoinExecutorConfigurator$AkkaForkJoinTask.exec(AbstractDispatcher.scala:393) at scala.concurrent.forkjoin.ForkJoinTask.doExec(ForkJoinTask.java:260) at scala.concurrent.forkjoin.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:1339) at scala.concurrent.forkjoin.ForkJoinPool.runWorker(ForkJoinPool.java:1979) at scala.concurrent.forkjoin.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:107)
