TypeError when applying nix environment in Remote SSH

[siddharth-krishna]

Describe the bug
I am using this extension from VS Code on my macbook, and using the Remote SSH extension to open a workspace on a remote Ubuntu server. The wokspace has nix flakes set up. When I try to select a nix environment using this extension, the message "Applying environment" appears forever, but in the "Extension Host (Remote)" output pane I see the error:

2023-06-27 07:25:22.142 [error] TypeError: c.call is not a function
	at /home/sid/.vscode-server/extensions/arrterian.nix-env-selector-1.0.9/dist/main.js:2538:310

To Reproduce
Steps to reproduce the behavior:

1. Open a remote workspace.
2. Use the "Nix-Env: Select environment" command to select flake.nix
3. Open the Outputs pane and go to "Extension Host (Remote)"
4. See error

Expected behavior
I expect the nix environment to be activated so that I can use HLS for my project.

Environment:

• OS: macOS 13.4.1
• VS Code: 1.79.2

@arrterian Could I sponsor some work on this one? Let me know!

@arrterian @amadejkastelic This was auto-closed by PR #97 (v1.1.0), but I'm still getting this error:

[error] TypeError: c2.call is not a function
	at .vscode-server/extensions/arrterian.nix-env-selector-1.1.0/dist/index.js:26377:90

Is it certain that that PR fixed this issue?

Edit: It might be that I did it wrong, and only did Reload window instead of Restart extension host in vscode after installing v1.1.0. Doing the latter seems to make it go away, I'll report if it stays gone.

I assumed this was caused by no flake support. If not, feel free to reopen the issue and I'll try to take a look.

@amadejkastelic I don't use any flakes. But after upgrading and then doing Restart extension host, it hasn't reoccurred yet, so I suspect that's needed to really load the new code properly (I'm using it in vscode's Remote Development feature, so that may also affect the code reloading).

I'll reopen if it re-occurs after this -- thank you!

@amadejkastelic OK, I think we should reopen it.

When I reboot my laptop and re-open vscode and re-connect to my Remote SSH development machine, I get first thing:

2025-05-23 22:42:25.286 [error] TypeError: c2.call is not a function
	at /root/.vscode-server/extensions/arrterian.nix-env-selector-1.1.0/dist/index.js:26377:90

Only Restart extension host fixes that.
