Waiting for external conditions before running workflow

I recommend using activity retry or always running a heartbeating activity for such a check. For more ideas, see this post.

BTW why do you use Timer with Selector instead of just workflow.Sleep?

timer := workflow.NewTimer(tCtx, time.Hour*24)
		selector.AddFuture(timer, func(f workflow.Future) {
	 
			err = monitor.Check(ctx, time.Time{}, time.Time{}, false)
			if err != nil {
				cancel()
			}
		})

Can be reduced to:

err := workflow.Sleep(tCtx, time.Hours * 24)
if err != nil {
   // handle cancellation
}
err = monitor.Check(ctx, time.Time{}, time.Time{}, false)
