It's a Rust build so not sure what node has to do with it, though I'm very unfamiliar with the internals of this project.

This shouldn't be related to the Rust subsystem I think but rather a more general issue I believe. But something might have changed that might have broken the code in the Rust subsystem. I'm not exactly sure why however. If you post a flake here I can debug it.

Does 0131c22 fix your issue?

[johnae]

Thanks @yusdacra. Seems that fixes the issue.
