Android Duktape NullPointerException while Internet is not there

Question

I am getting a null Exception when there is no internet on my mobile.

it is showing error here:

val results: String? = jsBinder.androidWrapper(functionName, gson.toJson(input))

• input is Any type

• functionName is a string type

• gson is a GSON type
