Circular declaration

[renews]

I think you need to change

use NewRelic.Plug.Repo, repo: MyApp.Repo`

Looks like it is conflicting with the defined module.

defmodule MyApp.Repo do
  use Ecto.Repo, otp_app: :my app

  defmodule NewRelic do
    use NewRelic.Plug.Repo, repo: MyApp.Repo
  end
end

Gives this error

@renews Thank you for the report. Please, try to replace it with the following code:

  defmodule NewRelic do
    use Elixir.NewRelic.Plug.Repo, repo: MyApp.Repo
  end
