Helix Integration No Longer Works in v3.11.0+

[Joe-Zer0]

Prerequisites

• I have written a descriptive issue title.
• I have searched all open and closed issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with PowerShell Editor Services itself and does not reproduce in a standalone PowerShell instance, and is not an issue with my editor.
• I have verified that I am using the latest version of PowerShell Editor Services.
• If this is a security issue, I have read the security issue reporting guidance.

Summary

I am using the Helix editor (https://github.com/helix-editor/helix).
If I download the v3.10.0 release zip and extract it in C:\tools with the following config, then it works as expected. Meaning I get code analysis and suggestions within the editor. If I try the same thing with v3.11.0 or anything later including the latest v4.2.0, then it does not work. Meaning there is no code analysis or suggestions displaying within the editor. Please let me know what other information I can provide to help.

My languages.toml looks like this for powershell.

[[language]]
name = "powershell"
scope = "source.ps1"
file-types = ["ps1", "psm1"]
roots = [".git"]
comment-token = "#"
indent = { tab-width = 4, unit = "    " }
language-servers = ["powershell-editor-services"]

[language-server.powershell-editor-services]
command = "pwsh"
args = ["-NoLogo", "-NoProfile", "-Command", "C:\\tools\\PowerShellEditorServices\\PowerShellEditorServices\\Start-EditorServices.ps1 -BundledModulesPath C:\\tools\\PowerShellEditorServices -SessionDetailsPath C:\\tools\\PowerShellEditorServices\\PowerShellEditorServices.sessions.json -LogPath C:\\tools\\PowerShellEditorServices\\PowerShellEditorServices.log -FeatureFlags @() -AdditionalModules @() -HostName helix -HostProfileId 0 -HostVersion 1.0.0 -Stdio -LogLevel Normal"]

Hi there,

I looked through v3.10.0...v3.11.0 and couldn't spot anything that would affect the startup of the server, so my best guess is currently a machine issue, specifically around trusting the module (see PowerShell Signing. Specifically here in your logs:

2025-01-26 10:10:26.020 -06:00 [VRB] Setting execution policy to "RemoteSigned"
2025-01-26 10:10:32.918 -06:00 [VRB] Could not write to output handler, perhaps serialization failed?

That's where at startup the server attempts to set the execution policy appropriately such that the included bundled modules can be imported. Can you set your execution policy to "Bypass" when starting the PowerShell process? That would mean adding to args like this:

args = ["-NoLogo", "-NoProfile", "-ExecutionPolicy", "Bypass", "-Command", ...]

You may also want to try using Unblock-File recursively on the downloaded folder.

Could you try this and let me know? Thanks!

Running Set-ExecutionPolicy Bypass in the PowerShell session before starting Helix did work.
Setting it back to "RemoteSigned" and updating the config like args = ["-NoLogo", "-NoProfile", "-ExecutionPolicy", "Bypass", "-Command", ...] did not work.
Running Get-ChildItem C:\tools\PowerShellEditorServices\ -Recurse | Unblock-File did work.
Just Unblocking the directory I want to trust seems like the best solution to me. I will add this to the documentation on Helix's wiki https://github.com/helix-editor/helix/wiki/Language-Server-Configurations#powershell
Thank you for your help!

Glad to here it!
