I keep getting this error:

From Java SDK:

I started getting it whenever I restarted working for the day (i.e. first time each day) with the Java SDK. But now I’m seeing it repeatedly on Swift too, which didn’t used to happen.

Nothing gets logged on the server side:

SportsCarnivalPro2_logs_20230120050749.json (77.9 KB)

To clear the error, I can delete the local realm, of course. But I shouldn’t have to - I have not made any schema changes or anything!

Please help!

Hello! It’s hard to determine what’s going on here without some more logging. Could you set the log level for your app to ALL and send the logs when it fails with this error?

Docs for how to do this for Swift & Java:

Hello, thanks for sending over the logs. From what I can tell, your local Realm may have become corrupted. Did you at any point copy the Realm file and try to re-use it?

To fix this, I would recommend terminating and re-enabling Sync. If that is not an option, a pastebin (or similar) containing the full client logs would be useful.

Hope this helps!
