Crash ios app when connect tapjoy with "options = null"

I am using tapjoy_offerwall: ^14.4.0 when doing Tapjoy.connect ios app crash with error do
var options = args["options"] as! [String: Any]?

https://github.com/Tapjoy/flutter-sdk/blob/b8230058272566c1eb8e6b31a452a9b41cc63812/ios/Classes/TapjoyOfferwallPlugin.swift#L172C5-L172C53

I think options variable shouldn't crash like this?
