Entering ‘design mode’ of an ignition report i have a several minute ‘loading’ delay, then the following error is raised (full details also below), ``` ExecutionException: com.inductiveautomation.ignition.client.gateway_interface.GatewayException: Read timed out caused by GatewayException: Read timed out caused by SocketTimeoutException: Read timed out Ignition v8.0.15 (b2020072213) Java: Azul Systems, Inc. 11.0.6 ``` After 'ok’ing that, the design screens appear ok, except the key browser only shows ‘builtins’, and nothing at all from the report data (calculation queries, etc) Entering report ‘preview’ i get a white screen with ‘java.util.concurrent.ExecutionException: java.lang.IndexOutOfBoundsException: Index 0 out of bounds for length 0’ … and no report preview This has suddenly happened for all the reports i have setup, not just the one i have been working on today. HOWEVER when create a new ‘test’ report, the key browser is fully populated, and there are no similar problems entering preview or design mode - everything with that works ok. What has happened? and How do i fix it ? Thanks ```auto java.util.concurrent.ExecutionException: com.inductiveautomation.ignition.client.gateway_interface.GatewayException: Read timed out at java.base/java.util.concurrent.FutureTask.report(Unknown Source) at java.base/java.util.concurrent.FutureTask.get(Unknown Source) at java.desktop/javax.swing.SwingWorker.get(Unknown Source) at com.inductiveautomation.reporting.designer.workspace.design.SampleData$SampleDataLoader.done(SampleData.java:145) at java.desktop/javax.swing.SwingWorker$5.run(Unknown Source) at java.desktop/javax.swing.SwingWorker$DoSubmitAccumulativeRunnable.run(Unknown Source) at java.desktop/sun.swing.AccumulativeRunnable.run(Unknown Source) at java.desktop/javax.swing.SwingWorker$DoSubmitAccumulativeRunnable.actionPerformed(Unknown Source) at java.desktop/javax.swing.Timer.fireActionPerformed(Unknown Source) at java.desktop/javax.swing.Timer$DoPostEvent.run(Unknown Source) at java.desktop/java.awt.event.InvocationEvent.dispatch(Unknown Source) at java.desktop/java.awt.EventQueue.dispatchEventImpl(Unknown Source) at java.desktop/java.awt.EventQueue$4.run(Unknown Source) at java.desktop/java.awt.EventQueue$4.run(Unknown Source) at java.base/java.security.AccessController.doPrivileged(Native Method) at java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(Unknown Source) at java.desktop/java.awt.EventQueue.dispatchEvent(Unknown Source) at com.inductiveautomation.snap.swing.RibsEventQueue.dispatchEvent(RibsEventQueue.java:96) at java.desktop/java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.desktop/java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.desktop/java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.desktop/java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.desktop/java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.desktop/java.awt.EventDispatchThread.run(Unknown Source) Caused by: com.inductiveautomation.ignition.client.gateway_interface.GatewayException: Read timed out at com.inductiveautomation.ignition.client.gateway_interface.GatewayInterface.newGatewayException(GatewayInterface.java:351) at com.inductiveautomation.ignition.client.gateway_interface.GatewayInterface.getResponse(GatewayInterface.java:530) at com.inductiveautomation.ignition.client.gateway_interface.GatewayInterface.sendMessage(GatewayInterface.java:283) at com.inductiveautomation.ignition.client.gateway_interface.GatewayInterface.sendMessage(GatewayInterface.java:278) at com.inductiveautomation.ignition.client.gateway_interface.GatewayInterface.moduleInvokeSafe(GatewayInterface.java:897) at com.inductiveautomation.ignition.client.gateway_interface.ModuleRPCFactory$DynamicRPCHandler.invoke(ModuleRPCFactory.java:53) at com.sun.proxy.$Proxy54.getReportData(Unknown Source) at com.inductiveautomation.reporting.designer.workspace.design.SampleData$SampleDataLoader.doInBackground(SampleData.java:135) at com.inductiveautomation.reporting.designer.workspace.design.SampleData$SampleDataLoader.doInBackground(SampleData.java:112) at java.desktop/javax.swing.SwingWorker$1.call(Unknown Source) at java.base/java.util.concurrent.FutureTask.run(Unknown Source) at java.desktop/javax.swing.SwingWorker.run(Unknown Source) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.base/java.lang.Thread.run(Unknown Source) Caused by: java.net.SocketTimeoutException: Read timed out at java.base/java.net.SocketInputStream.socketRead0(Native Method) at java.base/java.net.SocketInputStream.socketRead(Unknown Source) at java.base/java.net.SocketInputStream.read(Unknown Source) at java.base/java.net.SocketInputStream.read(Unknown Source) at java.base/java.io.BufferedInputStream.fill(Unknown Source) at java.base/java.io.BufferedInputStream.read1(Unknown Source) at java.base/java.io.BufferedInputStream.read(Unknown Source) at java.base/sun.net.www.http.HttpClient.parseHTTPHeader(Unknown Source) at java.base/sun.net.www.http.HttpClient.parseHTTP(Unknown Source) at java.base/sun.net.www.protocol.http.HttpURLConnection.getInputStream0(Unknown Source) at java.base/sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at java.base/java.net.HttpURLConnection.getResponseCode(Unknown Source) at com.inductiveautomation.ignition.client.gateway_interface.GatewayInterface.getResponse(GatewayInterface.java:437) ... 13 more Ignition v8.0.15 (b2020072213) Java: Azul Systems, Inc. 11.0.6 ``` ---

Something is preventing your reports from being generated on the gateway and returned to the designer. Have you restarted your gateway since this started to happen? Can you get a thread dump from the gateway? Also, you should probably file a real support ticket for this; it’s possible this is some bug we’re already aware of, or that has been fixed since 8.0.15 (though I’m not immediately aware of one).
