in vscode for mix unit test, how to use `--only` parameter?-CodePudding

        (elixir_ls_debugger 0.10.0) lib/debugger/server.ex:1119: ElixirLS.Debugger.Server.launch_task/2

Then I changed launch.json to "--trace --only :external", similar error message as follows:

It is caused by syntax problem. Every paremeter should be one element as follows:

    "taskArgs": [
        "--trace", "--warnings-as-errors", "--only", "external"
