Import #30 "wasi_snapshot_preview1" "sock_accept": function import requires a callable

Hi. I'm having trouble executing PHP WASI under Cloudflare worker and can't understand what is actually wrong. It is always fails with the

Import #30 "wasi_snapshot_preview1" "sock_accept": function import requires a callable

Import #30 "wasi_snapshot_preview1" "sock_accept": function import requires a callable

. Is it some missing support for a standard on Cloudflare end or it needs to be compiled in special way? I would be grateful for any hints on the matter.

What I'm trying to achieve is to run php-cgi WASI build from https://github.com/vmware-labs/webassembly-language-runtimes/tree/main/php/v8.2.6
When I try to run wasmtime with the same binary it works without any issues

wasmtime php-cgi-8.2.6.wasm -i

wasmtime php-cgi-8.2.6.wasm -i

import { WASI } from '@cloudflare/workers-wasi';
import PHPCGI from './php-cgi-8.2.6.wasm';

export default {
    async fetch(request, _env, ctx) {
        const stdout = new TransformStream();
        const wasi = new WASI({
            args: ['-i'],
            stdout: stdout.writable,
        });

        const instance = new WebAssembly.Instance(PHPCGI, {
            wasi_snapshot_preview1: wasi.wasiImport,
        });

        ctx.waitUntil(wasi.start(instance));

        return new Response(stdout.readable, {
            headers: { 'content-type': 'text/html' },
        });
    },
};
