GitHub user PowerToThePeople111 edited a comment on the discussion: Some tasks in mapped tasks fail before starting, logs are empty
I experienced the same. Without sharing the exact code, I can say, that my dag is just a chain of sequential virtualenv tasks. The first one is mapped and exhibits the same problem as the issue-starter: some mapped tasks are in failed state although they have no start or end date. Also they do not even try to be re-executed: although retries are possible, they failed finally already on their first try. Another also strange thing I observed is, that initially there are 4 mapped tasks (1-4) queued. But instead of taking one of those initially mapped tasks as a second one to process, it will just take another one (the 5th) leaving the other ones waiting. Could it be, that this is causing the issue: like some kind of time out?
