SQL Sandbox Mode about excoveralls

[xadhoom]

this does not relate to coveralls, I use it in travis and gitlab-cli without any issue.

check you mix project settings and check that you have

      preferred_cli_env: [
        "coveralls": :test, "coveralls.detail": :test,
        "coveralls.post": :test, "coveralls.html": :test
      ]

I'm running into this as well with the following config

  def project do
    [
      app: :my_app,
      version: "0.0.1",
      elixir: "~> 1.7.3",
      elixirc_paths: elixirc_paths(Mix.env()),
      compilers: [:phoenix, :gettext] ++ Mix.compilers(),
      start_permanent: Mix.env() == :prod,
      aliases: aliases(),
      deps: deps(),
      test_coverage: [tool: ExCoveralls],
      preferred_cli_env: [
        coveralls: :test,
        "coveralls.detail": :test,
        "coveralls.post": :test,
        "coveralls.html": :test
      ],
      name: "MyApp",
      source_url: "https://repo.example/myrepo",
      docs: [
        main: "readme",
        extras: ["README.md"]
      ]
    ]
  end

and the following error

16:03:19.027 [error] GenServer MyApp.MyModule.MyGenserver terminating
