"Handler does not export a scheduled() function" - No matter how it's exported

Howdy, I'm struggling to use the CRON events for my worker; no matter how I export my scheduled fnc, the worker insists it does not exist. As I understand it, the export must be named exactly scheduled, so in my index.ts I have the following:

export const scheduled = async (controller: ScheduledController, env: Env) => {
    console.log('Scheduled function triggered:', controller.cron);
};

export const scheduled = async (controller: ScheduledController, env: Env) => {
    console.log('Scheduled function triggered:', controller.cron);
};

Yet when the CRON runs, I get Handler does not export a scheduled() function. If I try using export default then I get errors about the handler not having fetch. If I used a named export for fetch and the default for what would be the scheduled, I get a different error again: No event listener registered for scheduled events.. I feel I'm running in circles lol, any input would be appreciated, thanks.

I believe it needs to be the default export https://developers.cloudflare.com/workers/runtime-apis/handlers/scheduled/#syntax

When a Worker is invoked via a Cron Trigger, the scheduled() handler handles the invocation.

If I try using export default then I get errors about the handler not having fetch.

:NotLikeThis: Any suggestions? 😅 I'll try it again now and get the full error

Oh sorry it is late

export default {
  async fetch() {}
  async scheduled(event, env, ctx) {
    ctx.waitUntil(doSomeTaskOnASchedule());
  },
};

export default {
  async fetch() {}
  async scheduled(event, env, ctx) {
    ctx.waitUntil(doSomeTaskOnASchedule());
  },
};

Ahhh okay, I hadn't tried that, allow me a moment to edit, deploy, and CRON to test, ty! :pray_duck:
