    warning: function init/1 required by behaviour GenServer is not implemented (in module GiocciZenoh).

    We will inject a default implementation for now:

        def init(init_arg) do
          {:ok, init_arg}
        end

    You can copy the implementation above or define your own that converts the arguments given to GenServer.start_link/3 to the server state.

You have configured application :giocci_zenoh in your configuration file,
but the application is not available.

This usually means one of:

  1. You have not added the application as a dependency in a mix.exs file.

  2. You are configuring an application that does not really exist.

Please ensure :giocci_zenoh exists or remove the configuration.
