Use for queue and scheduled not supported

[JorritSalverda]

Working on trying to identify what causes a memory access out of bounds CompileError in some queue handlers - see cloudflare/workers-rs#374 - I stumbled upon the fact that I can't use recordCoredump for workers that handle queue events or cron triggers, since they lack a request object.

My entry.mjs file looks as follows:

import shim, { getMemory, wasmModule } from "../build/worker/shim.mjs"
import { recordCoredump } from "@cloudflare/wasm-coredump"

const timeoutSecs = 60;

async function fetch(request, env, ctx) {
  try {
    // see https://github.com/rustwasm/wasm-bindgen/issues/2724.
    return await Promise.race([
      shim.fetch(request, env, ctx),
      new Promise((r, e) => setTimeout(() => e("timeout"), timeoutSecs * 1000))
    ]);
  } catch (err) {
    console.error(err);
    const memory = getMemory();
    const coredumpService = env.COREDUMP_SERVICE;
    await recordCoredump({ memory, wasmModule, request, coredumpService });
    throw err;
  }
}

async function queue(batch, env, ctx) {
  try {
    // see https://github.com/rustwasm/wasm-bindgen/issues/2724.
    return await Promise.race([
      shim.queue(batch, env, ctx),
      new Promise((r, e) => setTimeout(() => e("timeout"), timeoutSecs * 1000))
    ]);
  } catch (err) {
    console.error(err);
    const memory = getMemory();
    const coredumpService = env.COREDUMP_SERVICE;
    await recordCoredump({ memory, wasmModule, request, coredumpService });
    throw err;
  }
}

async function scheduled(event, env, ctx) {
  try {
    // see https://github.com/rustwasm/wasm-bindgen/issues/2724.
    return await Promise.race([
      shim.scheduled(event, env, ctx),
      new Promise((r, e) => setTimeout(() => e("timeout"), timeoutSecs * 1000))
    ]);
  } catch (err) {
    console.error(err);
    const memory = getMemory();
    const coredumpService = env.COREDUMP_SERVICE;
    await recordCoredump({ memory, wasmModule, request, coredumpService });
    throw err;
  }
}

export default { fetch, queue, scheduled };

However the calls to recordCoredump from queue and scheduled fail with exception:

  "exceptions": [
    {
      "name": "ReferenceError",
      "message": "request is not defined",
      "timestamp": 1693489675116
    }
  ],

It would be nice if the request parameter was made optional and handled without error if it's not passed, so that I can perform core dumps for cron triggers and queue consumers.
