QuestionNullPointerException When Setting ClickListener on a RelativeLayout Pin

Hello there. I am setting a click listener on a relative layout. It works fine. But today I got couple of crashes on this click listener from the user. I set this click listener in the onCreate() function of the activity. Here is what my code looks like

@Override
protected void onCreate(Bundle savedInstanceState) {
    layoutHomeButton = findViewById(R.id.layoutHomeButton);
    layoutHomeButton.setOnClickListener(new View.OnClickListener() {  //  <===exception here
                @Override
                public void onClick(View view) {
                   // my code goes here
                }
            });
}

And following is the exception I get
java.lang.RuntimeException:
