Cookie not getting saved when used with kotlin and OKHTTP, while same works for Java and OKHTTPretrofit

Hi, I am using kotlin to do my android project. Im using this library on my other java projects on android and all of them works fine. But when I use this with kotlin the cookie is not getting saved. I want to know whether this has occured to you or do you know the work around for this issue?

I have manually checked using adb commands to read the shared prefrences. While on my java project the cokie is being set but here it isnt. Please respond fast
