Upgrade to 4.0.1

1

Heyo :slight_smile:

I’ve tried to upgrade to 4.0.1 from 3.9.6 with the ZIP on a IIS server, but I get:

The PSU log is saying:

Unhandled exception. System.ArgumentNullException: Value cannot be null. (Parameter 'name')
   at System.ArgumentNullException.Throw(String paramName)
   at System.Environment.ExpandEnvironmentVariables(String name)
   at Universal.Server.Program.CreateHostBuilder(String[] args, Options options) in C:\actions-runner\_work\universal\universal\src\Universal.Server\Program.cs:line 253
   at Universal.Server.Program.<>c__DisplayClass3_0.<Main>b__0(Options o) in C:\actions-runner\_work\universal\universal\src\Universal.Server\Program.cs:line 63

   at Universal.Server.Program.Main(String[] args) in C:\actions-runner\_work\universal\universal\src\Universal.Server\Program.cs:line 52

But I don’t have a path C:\actions-runner\

I’ve also run Get-ChildItem -Recurse | Unblock-File

I’ve also installed .NET 7.0 hosting bundle, and rebooted afterwards.

Not sure what the next step is :confused:

I am also getting the same issue djo. Will be grateful for any suggestions on here :slight_smile:

If you didn’t replace the appsettings.json file during the upgrade, you will need to ad the SystemLogPath setting.

"SystemLogPath": "%ProgramData%\\PowerShellUniversal\\systemLog.txt",
