ByteBuddy throws java.lang.IllegalStateException - Cannot locate field named name for class

I am trying to explore and understand the bytebuddy library to create advice for one of the method. But I am encountering an exception upfront as below which seems a bit weird as given below:

Exception in thread "main" java.lang.IllegalStateException: Cannot locate field named name for class org.purbarun.proxy.MyService$ByteBuddy$8XL9Iy3U

My code as given below should be very simple and straightforward as I am quite new to this:

public class MyService {
    public void myMethod(String args) {
        System.out.println(args);
    }
}

public class MyServiceInterceptor {
    @OnMethodEnter
    static void enter(@This Object thisObject,
            @Origin String origin,
            @Origin("#t #m") String detaildOrigin,
            @AllArguments Object[] ary,
            @FieldValue(value = "name", readOnly = false) String nameField){
        System.out.println("test");
    }
}

public static void main(String[] args) throws IllegalAccessException, InvocationTargetException, NoSuchMethodException, SecurityException, InstantiationException, IllegalArgumentException {
        Class<? extends MyService> type=new ByteBuddy()
          .subclass(MyService.class)
          .method(ElementMatchers.isMethod()).intercept(Advice.to(MyServiceInterceptor.class))
          .make()
          .load(MyService.class.getClassLoader())
          .getLoaded();
        
        String returnVal = (String)type.getDeclaredMethod("myMethod", String.class).invoke(type.getDeclaredConstructor().newInstance(), "Method");
        System.out.println("return value: " + returnVal);
    }

Not sure if I am doing kind of silly mistakes which I am not able to get.

Can anyone from the community help me out to figure out the error.

If you don't have a name field in MyService simply remove the @FieldValue parameter from your advice:

@OnMethodEnter
static void enter(
        @This Object thisObject,
        @Origin String origin,
        @Origin("#t #m") String detaildOrigin,
        @AllArguments Object[] ary
        // Remove: @FieldValue(value = "name", readOnly = false) String nameField
) {
    System.out.println("test");
}

If you do plan to access a field from the original class via @FieldValue, ensure that the field exists in the class:

public class MyService {
    public String name; // Must exist to be accessible with @FieldValue
    public void myMethod(String args) {
        System.out.println(args);
    }
}
