Sometimes, events are unable to be uploaded to the warehouse. This can happen
for a variety of reasons; for example, the warehouse credentials may be
invalid, or your event schema may have evolved to have incompatible types.
Regardless, Hightouch ensures that data is never dropped.
Invalid data is automatically retried for at least 48 hours. If the data issue
has still not been resolved, the invalid events are stored so that they can be
replayed at a later date.
Replaying events is done via the "Archived Failures" screen.
