In Visual Studio Code only, running mix dialyzer does not find a problem:

defmodule BlahBlah.Repo do
  use Ecto.Repo,
    otp_app: :blahblah,
    adapter: Ecto.Adapters.Postgres
end

Callback info about the Ecto.Repo behaviour is not available.

There is another question about this exact error in Phoenix framework, but I’m not using Phoenix and there didn’t seem to be a resolution.

Same warning when I use Ecto.Type.

The repo is defined exactly as Ecto says on hexdocs. How do I make this warning go away? It is acceptable if I can just suppress that particular warning for that particular module.
