import {

  Console
} from "effect";

// A helper function to log output at each interval of the schedule
const log = <A>(
  action: Effect.Effect<A>,

): void => {
  let i = 0

  Effect.gen(function* () {

            Schedule.intersect(Schedule.recurs(10)),
            Schedule.tapOutput(([Out]) =>
              Console.log(
                i === 11 ? "..." : [new Date(Out[0]), new Date(Out[1])]
              )
            )
          )
        ),
        Effect.fork
      )
    yield* TestClock.adjust(Infinity)
    yield* Fiber.join(fiber)
  }).pipe(Effect.provide(TestContext.TestContext), Effect.runPromise)
}

// Build a cron that triggers at 4:00 AM
// on the 8th to the 14th of each month
const cron = Cron.unsafeParse("0 0 4 8-14 * *", "UTC")

// Convert the Cron into a Schedule
const schedule = Schedule.cron(cron)

// Define a dummy action to repeat
const action = Effect.tryPromise(() => {
  console.log('started');
  // Simulate work
  return new Promise(resolve => setTimeout(resolve, 500));
}).pipe(Effect.andThen(Console.log('Done')), Effect.catchAll(e => Console.error(e)));

// Log the schedule intervals
log(action, schedule)
/*
Output:
Started
Done
IllegalArgumentException: Invalid date
*/

npx tsx src/index.ts

What is the expected behavior?

Simulate time progression and run cron jobs without crashing

What do you see instead?

started
Done
node:internal/process/promises:394
    triggerUncaughtException(err, true /* fromPromise */);
