WebAssembly.instantiate(): invalid value type

[1226085293]

main.mbt

pub fn now() -> Int = "Date" "now"

fn main {
  let startTime = now()
  let mut value = 0
  for index = 0; index < 10000000; index = index + 1 {
    value = value + 1;
  }
  println(now() - startTime)
  // println(@lib.hello())
}

Usage:

// 读取 WebAssembly 文件
const wasmBuffer = fs.readFileSync("./wasm/main.wasm");

// 使用 WebAssembly.instantiate 直接实例化
//@ts-ignore
const wasmModule = await WebAssembly.instantiate(wasmBuffer, {
    Date: {
        now: () => Date.now(),
    },
    now: () => Date.now(),
});

Error:

Error instantiating WebAssembly module: CompileError: WebAssembly.instantiate(): invalid value type 0x77 @+12 {stack: 'CompileError: WebAssembly.instantiate(): invalid value type 0x77 @+12', message: 'WebAssembly.instantiate(): invalid value type 0x77 @+12'}

Note: There is no error if the now function is not used.

Can not reproduce. Are you using Node 22 that supports wasm gc?

Test NodeJs Project: ts_test.zip

My Node version supports GC, because I had this problem and upgraded my Node version, then it was the problem now

System information: Windows 11 Professional.23H2

Node 20 does not support GC. It has to be enabled with an experimental flag, and the support was unstable. The support was added in Node 22.

I will try using Node22 later
