hello, I have a handle_info function on my LiveView which checks user_logout with broadcast or Process.send_after every 3 sec. but redirect doesn’t work and just reload current page , it should be noted I want to load a router of my controller
def handle_info({:user_logout, user_id}, socket) do
socket =
if user_id == socket.assigns.user_id do
redirect(socket, to: Routes.auth_path(socket, :login))
else
socket
end
{:noreply, socket}
end
it just shows me:
[debug] LiveView session was misconfigured or the user token is outdated.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) Ensure the `protect_from_forgery` plug is in your router pipeline:
plug :protect_from_forgery
5) Define the CSRF meta tag inside the `<head>` tag in your layout:
<%= csrf_meta_tag() %>
6) 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}});

Hi! This redirect worked for me:
APB9785
Is
handle_infoeven receiving the message? My first guess is that the function which broadcasts{:user_logout, user_id}is crashing the LV process, and the message is never getting sent.shahryarjb
Yes I had a logical error
