Output '{workspaceRoot}/test/{projectRoot}' is invalid. When {projectRoot} is '.', it can only be used at the beginning of the expression.

Current Behavior

I'm facing a sudden issue and it's most likely coming from an vitest.config.ts file in my root, which was there for a while as a template.

Running the "test" target now produces

NX Output '{workspaceRoot}/test/{projectRoot}' is invalid. When {projectRoot} is '.', it can only be used at the beginning of the expression.

with the following configuration

    "test": {
      "cache": false,
      "dependsOn": ["build"],
      "inputs": ["default", "^default"],
      "outputs": ["{workspaceRoot}/test/{projectRoot}"]
    },

And the failing project is my workspace, the root project @myworkspace/root.

Now the dilemma:

1. I can't remove {workspaceRoot} from the test output config, as it is mandatory
2. I can't remove the name of the root package.json, as it is mandatory
3. I don't have a project.json in root
4. I don't have a test script in root package.json
5. I like to use test target defaults for all my projects, but test target makes no sense for root

So my next idea was to comment out the vitest.config.ts and it made the issue disappear.

Expected Behavior

Not sure if the sheer presence of a vitest.config.ts file in the root should cause an issue that is revealing a dilemma.
