Render Expects Template to be a String
Hi, I am writing an authentication plug, upon failure I am rendering to 403 error page
case claims do
{:ok, claims} ->
conn
|> put_status(200)
_ ->
conn
|> render("forbidden.html")
|> halt()
end
It gives me this error
** (ArgumentError) render/2 expects template to be a string, got: %Plug.Conn{adapter: {Plug.Cowboy.Conn, :...}, assigns: %{}
I don’t know what I am doing wrong here, Any help would be highly appreciated!

As I was rendering the user to error page so what I did is create a render function in View and render template there:
def render("403.html", _assigns) do
render("forbidden.html", %{})
end
and in my authentication pipe:
case claims do
{:ok, claims} ->
conn
|> put_status(200)
_ ->
conn
|> put_status(403)
|> put_view(MyAppWeb.PageView)
|> render("403.html")
|> halt()
end

Are you sure you are using correct render/2 function? Especially as in this case you should use put_view/2 or render/3.
