Hey there!

Just a quick note: Usually people prefer building a Release first and deploying that instead of installing Elixir and mix and then using mix phx.server. Check out the docs on Releases here:
https://elixir-lang.org/getting-started/mix-otp/config-and-releases.html

To address your immediate issue, did you make sure to a) install and build your assets (npm run deploy --prefix ./assets) and b) compile your assets with mix phx.digest?

I also recommend you take a look at the Deployment Guide from Phoenix:

In case the issue is actually related to the generation of absolute URLs: You might have to change the URL configuration from

config :tilex, TilexWeb.Endpoint,
  url: [host: "localhost"],

to something like

config :tilex, TilexWeb.Endpoint,
  url: [host: "example.com", scheme: :https],

(see Phoenix.Endpoint — Phoenix v1.8.8)

Generally I would probably write this something more like:

base = System.get_env("EDGE_URL") || System.get_env("HOST") || "https://stoiven-til.herokuapp.com"
static_url =
  URI.parse(base)
  |> Map.from_struct()

But calling Map.from_struct on a %URI{} seems highly atypical. Usually I would call to_string on the %URI{} to get out a plan URL (e.g. "https://stoiven-til.herokuapp.com"), but if you wanted that in this case you would not even need URI.parse unless you’re using it for validation. Can you show how you’re using static_url?

For the other issues I think you should post a new topic, and make sure to include the implementation of the controllers (along with the exceptions).

Well what did ya know..I should def be reading more . I appreciate the help! I got it up and running now!
