Script is:

import { init, Wasmer, initializeLogger } from "@wasmer/sdk/node";

async function run() {
  await init();

  let cowsay = await Wasmer.fromRegistry("cowsay");

  let instance = await cowsay.entrypoint.run({ args: ["hello world"] });
  const output = await instance.wait();

}
run();

Getting the same error with this script, based on the example in the README:

import {init, Wasmer} from "@wasmer/sdk/node"

async function run() {
    await init()

    const pkg = await Wasmer.fromRegistry("python/python")
    const instance = await pkg.entrypoint.run({
        args: ["-c", "print('Hello, world!')"],
    })
    const { code, stdout } = await instance.wait()
    console.log(`Python exited with ${code}: ${stdout}`)
}

run()
