I am looking to implement passing the user agent to liveview based on this article https://fly.io/phoenix-files/pass-user-agent-info-to-your-liveview/

The suggested change is

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

I end up with the following error using Phoenix 1.7.0 and Elixir 1.14.3

== Compilation error in file lib/my_app_web/endpoint.ex ==
** (ArgumentError) expected a keyword list as the second argument, got: [:user_agent, {:connect_info, [session: [store: :cookie, key: "_my_app_key", signing_salt: "S+qhbMV3"]]}]

    (phoenix 1.7.0) expanding macro: Phoenix.Endpoint.__before_compile__/1
    lib/my_app_web/endpoint.ex:1: PetalProWeb.Endpoint (module)

Any help is appreciated.

The post has a typo. The :user_agent atom should be within the :connect_info config, not outside of it.

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