Deno failed to run with WasmGC #22861
Description
Version:
deno 1.41.2 (release, aarch64-apple-darwin)
v8 12.1.285.27
typescript 5.3.3
Search words:
- WasmGC
- WASM Reference types
Minimal reproducible code:
import init, { format } from "npm:@wasm-fmt/dart_fmt";
await init();
const input = `void main() { print('Hello, World!'); }`;
const formatted = format(input, "main.dart");
console.log(formatted);Expected output:
void main() {
print('Hello, World!');
}
Actual output:
error: Uncaught (in promise) Exception [WebAssembly.Exception] {}
Note: as WasmGC will introduced and enabled in Node@22, which has not been released yet, I am unable to verify its proper functioning within Node.
However, the following code has been confirmed to run successfully in Chrome.
