operation is not valid due to current state of object in Unity 3d

Question

I am new to unity and practicing transform movements on camera. The code for the c# script that I am applying on it is.

using UnityEngine;
using System.Collections;
using System.Collections.Generic;


public class HelloWorld : MonoBehaviour {


    public float speed = 2f;
    // Use this for initialization
    void Start () {

    }

    // Update is called once per frame 
    void Update () {
        transform.Translate(new Vector3(speed,0,transform.position.z) * Time.deltaTime);

    }
}

but the console is showing errors stating:

I searched for the problems and managed to get that the debugger is unable to get any thing from top of stack. But i am unable to figure out how its related to particular code and where actual problem exist?
