VS Code Vitest extension fails to load configs with repeated spawn EINVAL errors

Open hafsahjilanee opened this issue 5 months ago • 5 comments

Describe the bug

I have a monorepo where each package is configured with Vitest. I’m able to run tests from the terminal without issues. However, since I want to debug tests, I installed the Vitest extension in VS Code.

The Vitest extension (v1.26.3) activates as expected, detecting multiple vitest.config.* files across the workspace.

However, when attempting to run Vitest (v3.2.2) using internal shims, the extension encounters repeated spawn EINVAL errors during config loading.

As a result, the extension fails to load any test configuration, preventing test discovery and execution.

The full stack trace shows ChildProcess.spawn throwing EINVAL during the config resolution process: [Error 9:47:48 AM] [Error Error] The extension could not load any config. Error: The extension could not load any config.

Reproduction

Steps to Reproduce:

Open workspace containing multiple Vitest config files.

Activate Vitest extension or open Vitest Explorer.

Observe errors in VS Code output / extension logs related to spawn EINVAL.
