In my Crashlytics report, i received these errors(i'm using 0.84.1):
Is there a way to solve these errors?
Please let me know if you need more information.

Seem to be the same with #1904
If you are using ProGuard, please update ProGuard rules(proguard-rules.pro).

The ProGuard configuration for Realm java 0.84.1 is described here https://realm.io/docs/java/0.84.1/#proguard

Thank you for the answer.
Upgrading my proguard rules now.
