> {code}
> Note the "failure" bit. The split shard couldn't add a replica. But when you use the request status API, it returns a "completed" status.
> Apparently, completed doesn't mean it was successful! In any case, it is very misleading and makes it very hard to properly use the Collection APIs. We need more investigation to figure out what other Collection APIs might be affected.
