It is because you are using old version of Dompdf. Upgrade your Dompdf as it has been fixed.
See commit about this fixed on Adapter/CPDF.php.

You try to access a variable without it first being defined. If you define it first, you won't get an error.
<?php
$x = new stdClass();
$y = $x->z; // gererates Notice in error_log
$x = new stdClass();
$x->z = 'assigned'; // now it is assigned
$y = $x->z; // no error
// or you could make your own class
class Whatever
{
public $z;
}
$x = new Whatever();
$y = $x->z; // it's there whether a value has been assigned or not

Calling a controller from another controller in codeigniter (ERROR) [duplicate]

This question already has answers here:
How to load a controller from another controller in codeigniter?
(10 answers)
Closed 4 years ago.
I have the Login_controller:
if ($query->num_rows() == 1){
$usuario = $query->row();
$this->load->library('../controllers/Dashboard_controller');
}
And I have the Dashboard_Controller:
public function index(){
$this->load->view("dashboard/Dashboard_view");
}
}
But, I got a message error:

What am I doing wrong?

Try this one
redirect('/dashboard/index');

This question was asked before.
Basically you are calling the controller but not the index function.
Please refer to : How to load a controller from another controller in codeigniter?
