Thanks, I will definitely check it out!

Hi, would you mind telling me which toolchain you are using? I wasn't aware that Kotlin has standalone support for wasm, I would love to give it a try if it's publicly accessible

[bashor]

@TianlongLiang Hi! Kotlin Multiplatform toolchain supports wasm out of the box. Check out https://kotl.in/wasm or https://kotl.in/wasm-examples.

I'm working on Kotlin/Wasm (with other folks), so feel free to reach out if you have any questions.

Please try #3447.

Hi, @wenyongh @TianlongLiang! Thanks for fixes, it really helped with attached examples.

Previous binaries was compiled with disabled EH on Kotlin side, after turning it on I got the a similar error.
Here is a new binary --kotlin-wasm-wasi-example-wasm-wasi.wasm.zip

@bashor Welcome. Could you upload the wast file also? It is a little complex to analyze the wasm file without wast info, I used the tool compiled from wasm GC MVP spec proposal, but it reports: decoding error: malformed section id.
