👋 I've got a simple list of schedules

👋 I've got a simple list of schedules like this in worker:

  "triggers": {
    "crons": ["* * * * *", "*/2 * * * *"]
  },

  "triggers": {
    "crons": ["* * * * *", "*/2 * * * *"]
  },

But when I deploy this, the value of controller.cron inside my worker's scheduled callback is always * * * * * - this makes it impossible to differentiate between the two different schedules. Is this a known issue? If so, is there any workaround?

I believe this means the example from the docs here doesn't work either? https://developers.cloudflare.com/workers/examples/multiple-cron-triggers/

    switch (controller.cron) {
      case "*/3 * * * *":
        // Every three minutes
        await updateAPI();
        break;
      case "*/10 * * * *":
        // Every ten minutes
        await updateAPI2();
        break;
      case "*/45 * * * *":
        // Every forty-five minutes
        await updateAPI3();
        break;
    }

    switch (controller.cron) {
      case "*/3 * * * *":
        // Every three minutes
        await updateAPI();
        break;
      case "*/10 * * * *":
        // Every ten minutes
        await updateAPI2();
        break;
      case "*/45 * * * *":
        // Every forty-five minutes
        await updateAPI3();
        break;
    }

Because 45 is divisible by 3, controller.cron would never match the third case

Oh wait, this behaviour ONLY seems to happen when using * * * * *

Note the /2 and /4 firing separately at the same time Okay, so a less severe bug 😌 A bug nonetheless. Where best to file this? Good shout - am trying it now Works So only * * * * * is poison
