socket is being accessed in the function body, hence the need to include it in the function head.
Current:
def maybe_track_user(

  •     product,*

  •     %{assigns: %{live_action: :show, user_token: user_token}}*

  •     ) do*

  •            if connected?(socket) do*

  •            user = Accounts.get_user_by_session_token(user_token)*

  •            # do tracking here!*
  • end*

Expected:
def maybe_track_user(

  •  product,*

  •  %{assigns: %{live_action: :show, user_token: user_token}} **= socket***

  •  ) do*

  •          if connected?(socket) do*

  •          user = Accounts.get_user_by_session_token(user_token)*

  •         # do tracking here!*

end
