ThingWorx ApplicationLog.log 中多次出现“执行 API 请求消息时出错，正在向调用方发送错误响应！”

• 当 Mashup 设置为使用GetProperties服务并启用“自动更新值（如果可以）”功能时，有时会看到以下消息： ThingworxStorage\logs\ApplicationLog.log ：

 Error executing API request message, sending error response to caller!

• 如果启用了堆栈跟踪，则可以在ThingworxStorage\logs\ ErrorLog.log 中看到以下内容：

   Error executing API request message, sending error response to caller! com.thingworx.communications.server.security.NotAuthorizedException: Unable to lookup security context because ThingWorx Session ID [XXXX] is no longer valid! at com.thingworx.communications.platform.security.ThingworxSessionCache.lookupSecurityContext(ThingworxSessionCache.java:104) at com.thingworx.communications.platform.modules.DispatchingServerCommunicationModule.processAPIRequestMessage(DispatchingServerCommunicationModule.java:389) at com.thingworx.communications.platform.modules.DispatchingServerCommunicationModule.process(DispatchingServerCommunicationModule.java:296) at com.thingworx.communications.server.endpoints.DispatchingServerEndpoint.messageReceived(DispatchingServerEndpoint.java:103) at com.thingworx.communications.server.connection.jsr356.AbstractServerConnection.onThingworxMessage(AbstractServerConnection.java:416) at com.thingworx.communications.server.connection.jsr356.AbstractServerConnection.onMessage(AbstractServerConnection.java:342) at sun.reflect.GeneratedMethodAccessor61.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.apache.tomcat.websocket.pojo.PojoMessageHandlerWholeBase.onMessage(PojoMessageHandlerWholeBase.java:80) at org.apache.tomcat.websocket.WsFrameBase.sendMessageBinary(WsFrameBase.java:582) at org.apache.tomcat.websocket.server.WsFrameServer.sendMessageBinary(WsFrameServer.java:131) at org.apache.tomcat.websocket.WsFrameBase.processDataBinary(WsFrameBase.java:541) at org.apache.tomcat.websocket.WsFrameBase.processData(WsFrameBase.java:300) at org.apache.tomcat.websocket.WsFrameBase.processInputBuffer(WsFrameBase.java:133) at org.apache.tomcat.websocket.server.WsFrameServer.onDataAvailable(WsFrameServer.java:82) at org.apache.tomcat.websocket.server.WsFrameServer.doOnDataAvailable(WsFrameServer.java:171) at org.apache.tomcat.websocket.server.WsFrameServer.notifyDataAvailable(WsFrameServer.java:151) at org.apache.tomcat.websocket.server.WsHttpUpgradeHandler.upgradeDispatch(WsHttpUpgradeHandler.java:148) at org.apache.coyote.http11.upgrade.UpgradeProcessorInternal.dispatch(UpgradeProcessorInternal.java:54) at org.apache.coyote.AbstractProcessorLight.process(AbstractProcessorLight.java:53) at org.apache.coyote.AbstractProtocol$ConnectionHandler.process(AbstractProtocol.java:860) at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1589) at org.apache.tomcat.util.net.SocketProcessorBase.run(SocketProcessorBase.java:49) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.lang.Thread.run(Thread.java:748)
