Error message when saving a page

Product: PowerShell Universal
Version: 2026.1.5

Running Universal in Windows from the MSI install and the built in web server.

I’m creating a new app that will have multiple pages. Whenever I save changes of one of the pages in the app I get this error message

 at UniversalDashboard.Execution.SessionDriveVariableProvider.get_HostState() in D:\a\powershell-universal\powershell-universal\src\UniversalDashboard\Execution\SessionDriveProvider.cs:line 54
   at UniversalDashboard.Execution.SessionDriveVariableProvider.GetContentWriter(String path) in D:\a\powershell-universal\powershell-universal\src\UniversalDashboard\Execution\SessionDriveProvider.cs:line 157
   at System.Management.Automation.SessionStateInternal.GetContentWriterPrivate(CmdletProvider providerInstance, String path, CmdletProviderContext context)

My changes seem to save correctly though.

Hi turnitoff_onagain,

Thank you for the details. My name is Ruben Tapia from Ironman Software support.

Based on what you shared, I can confirm that multi-page apps are a supported scenario in PSU. Since the page contents appear to save correctly, this may be an editor-side save issue rather than a full write failure, but I am not certain yet.

To help narrow it down, could you please confirm the following?

  • Does this happen on every page or only on one specific page?

  • Can you reproduce it with a brand new test app that has only 2 very simple pages?

  • Right after the error appears, what do you see under Apps > Info > Log for that app?

  • Could you also share the relevant entries from the PSU system log at the same time?

  • Please confirm whether the PSU service account has full read and write access to the repository path.

If possible, please also let us know whether editing the file externally and letting PSU reload it shows the same behavior.
