I’ve been playing with the Remote Execution smart cell, and it’s been mostly fantastic. Just about everything I was looking for when I made this offhand comment back in May. :slight_smile: I’m left with two major questions: I’m working on creating a LiveBook that will be mostly focused on intera…

[image] mbklein: I’d be happy to use secrets for them[1], but it looks like you can’t use a secret or variable for the node name. I suppose the alternative would be to create my own smart cell that uses my target runtime’s settings instead of allowing for user input. Can you please open up an…

@mbklein what OTP versions are you using on remote and locally?

[image] josevalim: Can you please open up an issue? Will do, thanks. [image] josevalim: Which error do you get? :slight_smile: Wow, I even had the error on my clipboard ready to go, and completely failed to hit paste. My test remote runtime’s startup log looks like this: Erlang/OTP …

I see. So you need to create a secret, choose it, and then you can replace its value dynamically inside the runtime using System.put_env/2.

[image] jonatanklosko: @mbklein what OTP versions are you using on remote and locally? OTP 26 on both. The only difference when I get the error is the Elixir patch version.

@josevalim @jonatanklosko super excited to see the remote smart cell. But I’ve been having some issues. I saw your PRs and reddit post around the fix for :eprc.call(node, fn -> :ok end) failing on differing OTP/elixir versions, yet I’m seeing the same issue on latest with and without the smart cel…

You need both nodes on 1.15.7+, which means it requires the same version for now but not for future versions.

Thanks for the reply and sorry for the confusion. What I’m saying is that the nodes are on 1.15.7. They all return the same value from System.build_info().

Can you call :erpc.call(node, :elixir, :module_info, []) on both nodes and let me know what it returns? Is the vsn attribute the same? Are the OTP versions exactly the same too? EDIT: Nevermind, I know what is wrong. The fix we provided for Elixir is not enough.

Can you folks please try Kino’s main? GitHub - livebook-dev/kino: Client-driven interactive widgets for Livebook · GitHub We have pushed a new approach that should work and be more robust across both Erlang and Elixir version changes.
