How to bind RigidBody to a script?

Question

C++ / C#

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

public class Rocket : MonoBehaviour
{
Rigidbody rigidBody;
    void Start()
    {
        rigidBody = GetComponent<Rigidbody>();
    }

    void Update()
        {
            processInput();
        }
    void processInput()
        {
            if(Input.GetKey(KeyCode.Space))
            {
                rigidBody.AddRelativeForce(Vector3.up);
                print("пробел");
            }
            if(Input.GetKey(KeyCode.A))
            {
                print("Поворот влево");
            }
            else if(Input.GetKey(KeyCode.D))
            {
                print("Поворот вправо");
            }
        }
}

In the screenshot in line 7, rigidBody lights up white, although it should light up blue, judging by the tutorial.
While writing, it lights up blue, but when I put a semicolon, it starts burning white.
RigidBody and script on the same object in the unit.

Change the theme of the vizhla - it will burn at least red)))
