LiveBook App in "local preview" sources config file from wrong directory?

Hi

I am using Livebook together with a mix project like this;
Mix.install(
[
{:gf_app, path: Path.join(DIR, “…”), env: :dev},
{:kino, “~> 0.14.2”},
… more dependencies …
],
lockfile: :gf_app,
config_path: :gf_app
)

Works great until I try to deploy as a local app using “local preview”. At that point, LB attempts to get config files from the autosave path…

** (File.Error) could not read file “/Users/xxx/Library/Application Support/livebook/autosaved/2024_12_05/config/config.exs”: no such file or directory

#cell:setup:1: (file)

Any idea of how to get this to work?

Thanks In advance!

Hey @TAS, this behaviour is expected since the app is not tied to the deployed notebook location. One thing you can do is store the path to app in a secret (or regular env var) and read it from there.

Thanks @jonatanklosko. I will try that. What I am really looking for is to hide the code cells and just show md text and kino UI elements and basically run the live-book in a “dynamic presentation mode” to explore some complex modeling scenarios where the code itself just becomes a distraction. After reading PR #2798 it seems like a good fit.
