LiveView Configuration Issue - LiveView session was misconfigured or the user token is outdated

Has anyone been able to get this working with LiveView or have any recommendations as to how I might debug this issue...

I am starting with https://github.com/dersnek/chirp as a working application

I get the following errors after setting everything up per the instructions... it seems like everything is as it should be

[debug] LiveView session was misconfigured or the user token is outdated.

1) Ensure your session configuration in your endpoint is in a module attribute:

    @session_options [
      ...
    ]

2) Change the `plug Plug.Session` to use said attribute:

    plug Plug.Session, @session_options

3) Also pass the `@session_options` to your LiveView socket:

    socket "/live", Phoenix.LiveView.Socket,
      websocket: [connect_info: [session: @session_options]]

4) Define the CSRF meta tag inside the `<head>` tag in your layout:

    <%= csrf_meta_tag() %>

5) Pass it forward in your app.js:

    let csrfToken = document.querySelector("meta[name='csrf-token']").getAttribute("content");
    let liveSocket = new LiveSocket("/live", Socket, {params: {_csrf_token: csrfToken}});

My endpoint.ex file has the following sections:

  ]
  ]
  socket "/socket", ChirpWeb.UserSocket,

  socket "/live", Phoenix.LiveView.Socket, websocket: [ connect_info: [session: @session_options]]
