JSON - no Response data, using Retrofit and Gson

Question

Issue: Request is being done(hits are increasing) but there is no Response. What I did so far: - I rechecked all the namings and type - Went through all similar StackOverflow questions

Log:

Attempted to deserialize a java.lang.Class. Forgot to register a type adapter?

Answer 1

As Jake mentioned, I had mistyped 'Classes' as 'Class'.

Answer 2

You are referenced java.lang.Class instead of com.vyshnav.trainfromto.model.Classes on this line:

private List<Class> classes = new ArrayList<Class>();
