public final class EmptyResultSetException extends RuntimeException

java.lang.Object
↳	kotlin.Throwable
	↳	java.lang.Exception
		↳	java.lang.RuntimeException
			↳	androidx.room.rxjava3.EmptyResultSetException

Thrown by Room when the query in a io.reactivex.rxjava3.core.Single DAO method needs to return a result but the returned result from the database is empty.

Since a io.reactivex.rxjava3.core.Single must either emit a single non-null value or an error, this exception is thrown instead of emitting a null value when the query resulted empty. If the io.reactivex.rxjava3.core.Single contains a type argument of a collection (e.g. Single<List<Song>>) the this exception is not thrown an an empty collection is emitted instead.
