How to configure a vitest.workspace.ts without having the root folder loaded (Workspace folder not found for file vitest.workspace.ts)

[WtfJoke]

I cant get a vitest workspace to work with our type of folder structure. Any help would be appreciated!

My project structure looks like that:

All these projects can also be opened individually and are self contained (its no monorepo).

My vscode.workspace.ts looks like that:

export default ["project1/vitest.config.ts"];

In my vs-code workspace projects.code-workspace Ive defined all projects like that:

"folders": [
		{
			"path": "project1",
			"name": "My cool project 1"
		},
		{
			"path": "project2",
			"name": "My cool project 2"
		}
],
"settings": {
		"vitest.workspaceConfig": "~/projects/vitest.workspace.ts",
}

Now the vitest extensions crashes with

[API] Using user workspace config: /home/manuel/projects/vitest.workspace.ts.
[Error Error] Workspace folder not found for file:///home/manuel/projects/vitest.workspace.ts. Does the file exist?
Error: Workspace folder not found for file:///home/manuel/projects/vitest.workspace.ts. Does the file exist?

If I add the root folder to vscode it seems to work.
Is there some way to make this work without adding the root folder to my vs code workspace?

I am afraid that it's not possible to do that with the current extension architecture. You need a workspace folder for every config file. Feel free to create an issue, it should be possible to rewrite that.
