Hello! This is an older project that I haven't maintained any in the last couple years. That said, it still starts up normally on my machine, could you provide some more details about your:

Operating system
elixir version
erlang version

That error looks like you're missing a dependency. Could you run mix deps.get and try again?

Thank you for your replay Dylan.

my OS: Mac OS Big Sur 11.6.2

What does erl --version show?

Based on this answer it looks like this app needs the phoenix_pubsub dependency updated to 2.0 for compatibility with the latest Erlang.

I'd welcome a PR bumping that up.

Hi @dlederle , a PR was up for this and I tested locally, https://localhost:4000/editor works as expected.

Thanks for your time to look at this, I'll continue to learn phoenix and liveview, this issue can be closed if the PR is OK.
