hi @vanvu08t2, we already solved this issue over intercom chat, but I'll share it here as well.
cancel_previous_submissions works only in conjunction with App Store submission. If submit_to_app_store is set to false (or is missing, which is equivalent to false), then there is nothing to cancel, and because of that validation error occurs.
