Android: Signup issue while using Kotlin

[uditunpluged]

I tried to signup a user using java your sdk in my kotlin based android project like this

fun signUpSocialUser(email: String, phoneNumber: String, fullname: String) {
        var session = mySocialApp.createAccount(email, phoneNumber + fullname, fullname)
        session.observeOn(Schedulers.io()).subscribeOn(Schedulers.io()).subscribe({
            Log.e("SOCIAL DATA", it.authenticationToken.toString())
        },
            {
                Log.e("SOCIAL ERROR", it.message)
            }, {
                Log.e("SOCIAL COMPLETE", "")
            })


    }

I am getting the exception and hence unable to proceed further.
SOCIAL ERROR: Reflection on built-in Kotlin types is not yet fully supported. No metadata found for public open val cause: kotlin.Throwable? defined in kotlin.Throwable[DeserializedPropertyDescriptor@4bb15c9]

Can you please give your SDK version?
