#ElixirLs + VSCode: error when running tests

Hello! I have a question that is more on the tooling side.
Whenever I try to run a test in the editor (for example, by pressing the "run" green sign to the left of the line number, I receive this error. My tasks are the default auto-generated:

{
    // Use IntelliSense to learn about possible attributes.

    "version": "0.2.0",
    "configurations": [
        {
            "type": "mix_task",
            "name": "mix (Default task)",
            "request": "launch",
            "projectDir": "${workspaceRoot}"
        },
        {
            "type": "mix_task",
            "name": "mix test",
            "request": "launch",
            "task": "test",
            "taskArgs": [
                "--trace"
            ],
            "startApps": true,
            "projectDir": "${workspaceRoot}",
            "requireFiles": [
                "test/**/test_helper.exs",
                "test/**/*_test.exs"
            ]
        },
    ]
}

How can I run a test inside of the editor? It's much more useful than just running mix test in console =-)

And what do you get in the terminal/console?

In the "debug console" I get:

Strange. Did you try mix deps.get?

If it is missing Plug.Builder, something is very wrong.
