When running tests, I get this error:

internal error in Neon module: Failed to instantiate module: Function("host module doesn\'t export function with name hc_crypto")

$ hc --version
hc 0.0.27-alpha1

Arch Linux

Hi there. This is most likely happening because you haven't updated your Cargo.toml files in your dna to match the latest alpha. Tell me if updating that resolves your problem.

No, that didn't

I've noticed this also happens for me when I forget to run the test command from within my Nix environment. I think it's because I have Rust installed natively in my system and there are some mismatched dependencies between it and the version provided by Nix.
