Upon downgrading to 1.4.1 everything works.

(i am following the "Build a real-time Twitter clone in 15 minutes with LiveView and Phoenix 1.5" tutorial)

Fixed. We were uising a function avai9lable only on Elixir v1.15+. Go with 1.5.1 or 1.4.1, both are fine. :)

Just to report back, everything is working fine now with 1.5.1 and Elixir 1.14. Thanks for the super fast feedback :)
