after Gradle build I am getting the details(where I am storing all the fetched data one by one) empty I think there is an issue with gettingRequest() function in the main kt file. Could anyone please help me by finding the issue?
success is not there in the api data so remove this
val success = it.getBoolean("success")
if(success)
