Hammered this as a dupe of the NPE canonical as it lacks a [mcve]. If you post an MCVE and it still indicates this isn't a dupe, I'll reopen it — Zoe, Dec 12 '20 at 22:56

I can't post a comment yet, did you enabled proguard? make sure you add all of your models to proguard rules. And please provide your question with your source code.

-keep class com.yourapps.yourpackage.model.** { *; }
