tic-tac-toe tutorial error

Unity Engine
1

at this link of tutorial there’s a section where i have to create a gaveover function like this:

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

public class GameController : MonoBehaviour
{
    private string playerSide;

    public Text[] buttonlist;

    void Awake()
    {
        SetGameContollerReferenceOnButtons();
        playerSide = "X";
    }

    void SetGameContollerReferenceOnButtons ()
    {
        for (int i = 0; i < buttonlist.Length; i++)
        {
            buttonlist[i].GetComponentInParent<GridSpace>().SetGameControllerReference(this);
        }
    }

    public string GetPlayerSide()
    {
        return playerSide;
    }

    public void EndTurn ()
    {
        if (buttonlist [0].text == playerSide &&
            buttonlist [1].text == playerSide &&
            buttonlist [2].text == playerSide)
        {
            GameOver();
        }
    }

    void GameOver ()
    {
        for (int i = 0; i < buttonlist.Length; i++)
        {
            buttonlist[i].GetComponentInParent().interactable = false;
        }
    }
}

but

void GameOver ()
    {
        for (int i = 0; i < buttonlist.Length; i++)
        {
            buttonlist[i].GetComponentInParent().interactable = false;
        }
    }

or to be more specific GetComponentInParent() gives me an error in vs saying:

type arguement for method 'Component.GetComponentInParent() cannot be inferred from usage. try specifiying the type arguments specifically.

i did it by the text i don’t know where this error comes from or what it means. what should i do?

It’s because your missing the component you are trying to reference. If you look at first piece of code you put up, you have "GetComponentInParent() … ". Where as in you problem piece you just have “GetComponentInParent().” with no reference to the component you want.
