Correct Configuration

[X] I confirm that I have Wallaby configured correctly.

Current behavior

When following the current installation guide from here: https://github.com/elixir-wallaby/wallaby?tab=readme-ov-file#phoenix, specifically this section:

  if sandbox = Application.get_env(:your_app, :sandbox) do
    plug Phoenix.Ecto.SQL.Sandbox, sandbox: sandbox
  end

The following warning is issued:

    warning: Application.get_env/2 is discouraged in the module body, use Application.compile_env/3 instead
    │
 10 │   if sandbox = Application.get_env(:my_app, :sandbox) do
    │                            ~
    │
    └─ lib/myapp_web/endpoint.ex:10:28: MyAppWeb.Endpoint (module)

Expected behavior

The documentation has up-to-date instructions that do not result in a warning.
