Mike M (Apr 26 2025 at 01:40): Mike M (Apr 26 2025 at 01:40):We had issues in the browser calling into a WASM component, and eventually tracked it down to cargo-component v0.21.0 on (as far as we can tell) Apple Silicon. The built WASM seems to have issues in the adapter/shims, leading to call issues.
Issue logged here: https://github.com/bytecodealliance/cargo-component/issues/398
We've narrowed this down a lot, but if you need any more info or anything in the issue is unclear, we're happy to help further.
