Jackson and generic type reference

I want to use jackson json library for a generic method as follows:

public MyRequest<T> tester() {
    TypeReference<MyWrapper<T>> typeRef = new TypeReference<MyWrapper<T>>();  
    MyWrapper<T> requestWrapper = (MyWrapper<T>) JsonConverter.fromJson(jsonRequest, typeRef);
    return requestWrapper.getRequest();
}

public class MyWrapper<T> {

    private MyRequest<T> request;

    public MyRequest<T> getRequest() {
        return request;
    }

    public void setRequest(MyRequest<T> request) {
        this.request = request;
    }
}

public class MyRequest<T> {
     private List<T> myobjects;
        
     public void setMyObjects(List<T> ets) {
         this.myobjects = ets;
     }

     @NotNull
     @JsonIgnore
     public T getMyObject() {
         return myobjects.get(0);
     }
}

Now the problem is that when I call getMyObject() which is inside the request object Jackson returns the nested custom object as a LinkedHashMap. Is there any way in which I specify that T object needs to be returned? For example: if I sent object of type Customer then Customer should be returned from that List?
