I'm trying to setup Javers using a MongoDB repository. I'm using version 2.9.1 for both javers-core and javers-persistence-mongo.
However, when I try to commit an entity with a Boolean field, the following exception is thrown:
java.lang.IllegalArgumentException: unsupported JsonElement type - JsonPrimitive

Looking into the private static Object fromJsonElement(JsonElement jsonElement) method in javers-persistence-mongo-2.9.1/DocumentConverter, there are only conversion methods for the JsonPrimitives String and Number (not Boolean).
Am I missing some configuration here?
MWE:
public static void main(final String[] args) {
final TestEntity testEntity = new TestEntity();
testEntity.id = 12345L;
testEntity.testBoolean = true;
final MongoClient mongoClient = new MongoClient(...);
final Javers javers = JaversBuilder.javers()
.registerJaversRepository(new MongoRepository(mongoClient.getDatabase(...))).build();
javers.commit("testAuthor", testEntity); // Throws IllegalArgumentException
}
@Entity
static class TestEntity {
@Id
Long id;
Boolean testBoolean;
}
