Hmm ... 🤔
Gotta investigate this tomorrow morning. 🌅
Right now, gotta go be a Dad for a bit. ❤

Good morning internet! 👋
I think I know the answer to this one, without Googling ... 💭
I suspect it's because this project is using an older version of Elixir:

who/.github/workflows/ci.yml

Lines 26 to 30 in 9dbca75

	- name: Set up Elixir
	uses: erlef/setup-beam@v1 # https://github.com/erlef/setup-beam
	with:
	elixir-version: '1.14.3' # Define the elixir version [required]
	otp-version: '25.0' # Define the OTP version [required]

Going to try updating it to latest (v18.2) and see if that helps. 🧑‍💻

Good hunch. 👌
Closing. 📕
