File Validation with redirect

Good morning

I tried your code but i got still errors

This is my view code, I want to display the errors per each form field
This is working in EVERY other Controller/View Combination as posted below
Only the file upload will not work like this

PHP Code:

<?= form_label(lang('system/auth/pages/edit_profile_image.form.label.profile_image'), 'profile_image', ['class' => 'form-label']); ?>
<?= form_upload('avatar', set_value('avatar', $user->profile_image), ['autocomplete' => 'off', 'class' => 'form-control'.$viewData['bs_form_control_size'].((session()->has('validation') && session('validation')->hasError('avatar'))?' is-invalid':'').((session()->has('validation') && !session('validation')->hasError('avatar'))?' is-valid':''), 'id' => 'profile_image']); ?>
<?= (session()->has('validation') && session('validation')->getError('avatar'))?'<div class="form-text text-danger fw-bold">'.session('validation')->getError('avatar').'</div>':''; ?>

Why can i give class to session in other controllers and here its not workin?
