Problem with displaying errors

I have struggled with the ouput from "/application/Views/html/error_exception.php" because the following output is not intuitive

ErrorException #1

Uncaught TypeError: htmlspecialchars() expects parameter 1 to be string, boolean given in /home/john/www/johns-jokes.cf/app-welcome/Views/errors/html/error_exception.php:186 Stack trace: #0 /home/john/www/johns-jokes.cf/app-welcome/Views/errors/html/error_exception.php(186): htmlspecialchars(true, 8, 'UTF-8') #1 /home/john/www/ci2/CodeIgniter4/system/Debug/Exceptions.php(276): include('/home/john/www/...') #2 /home/john/www/ci2/CodeIgniter4/system/Debug/Exceptions.php(153): CodeIgniter\Debug\Exceptions->render(Object(TypeError), 500) #3 [inter

I modified  "html/error_exception.php" and the output is now far more readable:

TypeError
Argument 2 passed to add() must be of the type integer, string given, called in /home/john/www/johns-jokes.cf/app-welcome/Views/incs/_blurb.php on line 17    

PHP Code:

<?php NEAR Line #190 ?>
 
<?php if( FALSE ) : ?>
  <?php # START ORIGINAL SCRIPT ?>
    <?php foreach ($constants['user'] as $key => $value) : ?>
      <tr>
        <td><?= htmlspecialchars($key, ENT_IGNORE, 'UTF-8') ?></td>
        <td>
          <?php if (!is_array($value) && ! is_object($value)) : ?>
            <?= htmlspecialchars(  $value, ENT_SUBSTITUTE, 'UTF-8') ?>
          <?php else: ?>
            <?= '<pre>'.print_r($value, true) ; ?>
          <?php endif; ?>
        </td>
      </tr>
    <?php endforeach; ?>
  <?php # END ORIGINL SCRIPT ?> 

<?php else: 
  # START MODIFIED SCRIPT             
    foreach ($constants['user'] as $key => $value) : 
      echo '<tr><td>' ;
        echo htmlspecialchars($key, ENT_IGNORE, 'UTF-8');
      echo '</td><td>';
        if ( is_array($value) || is_object($value)) : 
          echo '<pre>'.print_r($value, true) .'</pre>'; 
        else:
          // FORCE (string) WHEN $value == BOOL OR INTEGER
          echo htmlspecialchars( (string) $value, ENT_SUBSTITUTE, 'UTF-8'); 
        endif; 
      echo '</td></tr>';
    endforeach; 
    # END MODIFIED SCRIPT 
  endif; 
?>

I also added a missing trailing </pre> where required in other parts of the script.

I would be grateful if someone could check the proposed changes.
