🧭 Collection of Kotlin APIs/tools to make using Realm Mobile database easier

Hi there 👋

Exception while computing database live data

Hi, I'm using your library for my project and I started to get this exception, so let me guide you through my project, inside of worker I'm checking some data:
override suspend fun doWork(): Result {
//code
val reversals = Database.transactionRepository().findAllReversals()
//code
}
and here is my findAllReversals:
suspend fun findAllReversals(): List {
return dispatch {
RealmFunction { realm ->
realm.copyFromRealm(
realm.where().equalTo("_status", StatusType.UNKNOWN.name).findAll()
).toList()
}
}
}
So at some point of accessing data sometimes (rarely) my app just crashes with error:
java.lang.RuntimeException: Exception while computing database live data.

Is there any walkarounds or fixes for that?

Crash in paging when calling adapter#refresh

Hi
While testing your paging library I noticed this crash when refreshing page:
