Add a default value NULL for $id in function definition itself.

If the function does not get any value, it will NULL

Check if the function is getting blank $id by using empty() function.

This way, your functionality of redirection will work properly.

Also, your warning will get removed.

public function index($id = NULL) {
 if (empty($id)) {  // when  $id value missing then redirect
  return redirect('service');
 }
 else {
  // some operation perform
 }
}

Change your function as below:

public function index($id = '') {
    if(empty($id)){
        return redirect('service');
    }else{
      // perform operation   
    }
}

Change your function as below:

public function index($id = '') {
    if(!trim($id)){  // when  $id value missing then redirect
        return redirect('service');
    }else{
    // some operation perform  
    }
}

You have to tell in your arguments the null value

public function index($id = null)

If no value, $id = null. So you can redirect easily.
