Generated password reset (mix phx.gen.auth) not working. UserResetPasswordController create never called

Hi everyone,

I’m trying to get the password reset function working from mix phx.gen.auth. Here is a snippet of the code:

defmodule LichtmalerElixirWeb.UserResetPasswordController do
  use LichtmalerElixirWeb, :controller

  alias LichtmalerElixir.Accounts

  require Logger

  plug :get_user_by_reset_password_token when action in [:edit, :update]

  def new(conn, _params) do
    Logger.alert("new")
    render(conn, "new.html")
  end

  #%{"user" => %{"email" => email}} =
  def create(conn, params) do
    Logger.alert("create")

    ...
    
    conn
    |> put_flash(
      :info,
      gettext("Wenn sich Ihre E-Mail-Adresse in unserem System befindet, " <>
        "erhalten Sie in Kürze Anweisungen zum Zurücksetzen Ihres Passworts.")
    )
    |> redirect(to: "/")
  end

  ...

Going to the page and calling the function with an existing email does not work as expected. The create function is never called, as you can see in the logs:

[info] GET /users/reset_password

  Parameters: %{"l" => "de"}

I have no idea how to debug this properly. Disabling plugs didn’t lead to any results.
Is this a known issue? Do you have any ideas how to solve this? I appreciate any help.

Thanks!
