Hi there,
First of all, I am not sure if this is the correct topic to post this under, but here goes.
We’re working with realm and mongo sync. At some point I started getting this error message from realm every time I would launch my iOS app in Xcode.
We figured out that it had to do with the partition that was used. Maybe the partition is somehow corrupted, but we can’t really tell from the logs. There is nothing in the logs on https://realm.mongodb.com/ … /logs, the only error we get is from the iOS app.
Creating a new partition and putting in the same content results in the same situation.
I am using
Xcode 12.2 (12B45b)
Realm v10.1.3
