The type of the Realm file was invalid


I’ve noticed that my iOS app stopped syncing to Realm. When I took a look at the logs in Realm Studio, I see the following errors:

HTTP response: 1c8b3326-3e6f-49a4-b822-f05463abcaef {"type":"","title":"The type of the Realm file was invalid.","status":400,"code":619}

I couldn’t find any information in the documentation on what this error means or how to resolve it. Any help would be appreciated.


I posted an explanation here:


Thanks for the quick reply. I’m not sure my problem is quite the same since I have never tried to do partial synchronization of my realm. This is how I’m setting up my synced realm:

        let syncConfiguration = SyncConfiguration(user: SyncUser.current!, realmURL: Constants.Realm.REALM_URL)
        let config = Realm.Configuration(syncConfiguration: syncConfiguration)
        let realm = try! Realm(configuration: config)
        self.defaultRealm = realm

        SyncManager.shared.errorHandler = { error, session in
            let syncError = error as! SyncError

It looks like this error is preventing my client from syncing any changes to the backend. Any recommendations on what to do to resolve the error?
