Hi, I copied a perspective project. In the copied project, every time I open a view in the designer (whether it's an existing view or a new one), the following error message box appears: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/7/6/76be9f23e2f14e2c40b631dbcde63c103c77fcae.png) Here you are the Details: ```auto com.inductiveautomation.ignition.common.script.JythonExecException Traceback (most recent call last): File "", line 2, in onPageStartup AttributeError: 'com.inductiveautomation.perspective.gateway.script' object has no attribute 'pageId' at org.python.core.Py.AttributeError(Py.java:178) at org.python.core.PyObject.noAttributeError(PyObject.java:965) at com.inductiveautomation.ignition.common.script.PyDelegateObject.noAttributeError(PyDelegateObject.java:316) at org.python.core.PyObject. __getattr__ (PyObject.java:959) at org.python.pycode._pyx3791.onPageStartup$1(:2) at org.python.pycode._pyx3791.call_function() at org.python.core.PyTableCode.call(PyTableCode.java:173) at org.python.core.PyBaseCode.call(PyBaseCode.java:306) at org.python.core.PyFunction.function ___call__ (PyFunction.java:474) at org.python.core.PyFunction. __call__ (PyFunction.java:469) at org.python.core.PyFunction. __call__ (PyFunction.java:464) at com.inductiveautomation.ignition.common.script.ScriptManager.runFunction(ScriptManager.java:846) at com.inductiveautomation.ignition.common.script.ScriptManager.runFunction(ScriptManager.java:828) at com.inductiveautomation.ignition.gateway.project.ProjectScriptLifecycle$TrackingProjectScriptManager.runFunction(ProjectScriptLifecycle.java:832) at com.inductiveautomation.ignition.common.script.ScriptManager$ScriptFunctionImpl.invoke(ScriptManager.java:1009) at com.inductiveautomation.ignition.gateway.project.ProjectScriptLifecycle$AutoRecompilingScriptFunction.invoke(ProjectScriptLifecycle.java:897) at com.inductiveautomation.perspective.gateway.script.ScriptFunctionHelper.invoke(ScriptFunctionHelper.java:158) at com.inductiveautomation.perspective.gateway.script.ScriptRunner.run(ScriptRunner.java:38) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.base/java.util.concurrent.FutureTask.run(Unknown Source) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at com.inductiveautomation.perspective.gateway.threading.BlockingWork$BlockingWorkRunnable.run(BlockingWork.java:58) at java.base/java.lang.Thread.run(Unknown Source) Caused by: org.python.core.PyException Traceback (most recent call last): File "", line 2, in onPageStartup AttributeError: 'com.inductiveautomation.perspective.gateway.script' object has no attribute 'pageId' ... 24 more Ignition v8.1.30 (b2023071408) Java: Azul Systems, Inc. 11.0.18 ``` Ignition version 8.1.30. ---

- Go to Project Browser \> Session Events \> Page Startup. - Have a look at line 2 and see if you can figure out what `pageId` it's looking for. If you can't figure out the problem then paste the script here (using the \ code formatting button. ---

Hi, there is no code. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/7/17d400587897c91ff7725ee3cb57f928be67fdcf.png) I'm pretty sure that it's a bug caused by the 'copy' action of the project. ---

What happens if you turn that into valid python? i.e., ```auto def onPageStartup(page): pass ``` ---

Tim, I asked about empty functions in the startup scripts and they're OK. You can't delete the definitions but if there's nothing in there it isn't a problem. The puzzle is why the script and `pageId` are mentioned in the error message. ---

Hi, the "tab" on scripts happens in all projects that i have but only in copied one cause the problems. ---

Just to be clearer. This anomaly doesn't cause issues at runtime but only in the designer. The only problem is the annoyance of having to dismiss the error message. I just wanted to report this potential bug. Before writing to you, I have already run several tests, including inserting 'print "hello"' statements within ALL session event scripts. ---

It is a puzzle. But the screenshot shows that the designer is unhappy. Adding a `pass` or a `print type(page)` is a sanity check that may provide a clue. Sounds like it has been tested already.
