I have a relationship User has_one Profile. In my User

defmodule Cal.Accounts.User do
  actions do
      defaults [:read]
      create :create_user_with_profile do
        argument :profile, :map do
          allow_nil? false
        end
        change manage_relationship(:profile, type: :create)
      end
  action

  relationship do
    has_one :profile, Cal.Accounts.Profile do
        destination_attribute :user_profile_id
    end
  end
...
end

In my form liveview

  def mount(_params, _session, socket) do
    form = Cal.Accounts.form_to_create_user_with_profile()
    socket =
      socket
      |> assign(:form, to_form(form))
      |> assign(:page_title, "New User with Profile")
    {:ok, socket}
  end

  def render(assigns) do
     ...
       <h4>User</h4>
        <.input field={form[:email]} label="Email" />
        <.input field={form[:user_name]} label="Name" />
        <.input field={form[:timezone]} label="Timezone" />

        <h4>User Profile</h4>
        <.inputs_for :let={form_profile} field={@form[:profile]}>
          <.input field={form_profile[:title]} label="Title" />
          <.input field={form_profile[:location]} label="Location" />
        </.inputs_for>
   end

The form renders the Email, Name and Timezone but the fields for profile Title and Location are not
