Hey, I tried to run https://github.com/linux-china/kotlin-wasm-node-demo after changing the version to 1.8.20-Beta, but was not able to. Basically, the command ~/.gradle/nodejs/node-v19.6.0-darwin-x64/bin/node --experimental-wasm-gc ~/kotlin-wasm-node-demo/build/js/packages/kotlin-wasm-node-example-wasm/kotlin/kotlin-wasm-node-example-wasm.mjs failed with the following error message:

file://~/build/js/packages/kotlin-wasm-node-example-wasm/kotlin/kotlin-wasm-node-example-wasm.uninstantiated.mjs:140
        const wasmModule = new WebAssembly.Module(wasmBuffer);
                           ^

Is this a known issue?

Hey, can you try it with v20.0.0-v8-canary202212266b2b946a63 as described in https://github.com/sdeleuze/kowasm#node?

[Svyatoslav Kuzmich [JB]]

This error could mean that V8 is too old, or it could be an unknown to us bug otherwise

Thanks for the fast response, the latest node version did the trick indeed 👍
