Printing all errors in one go within twig - symfony

Question

I want to print all errors in one go for all the fields however {{ form_errors(form) }} doesn't print anything so because of that I have to use if not form.vars.valid statement to print errors however all the individual error messages are being wrapped within <ul><li>Message</li></ul> which is annoying. I know that 'error_bubbling' => true solves the issue but creates another issue which is making field borders red.
How can I solve this issue? I simply want to print error without tags.
Note: I can use {{ form_errors(form.name)|striptags }} but it adds overheads cos my form is massive.
FORM TYPE
class BrandsType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->setAction($options['action'])
->setMethod('POST')
->add('name', 'text', array('label' => 'Name'))
->add('button', 'submit', array('label' => 'Submit'))
;
}
}
TWIG
{% extends '::base.html.twig' %}
{% block body %}
{{ form_start(form, {attr: {novalidate:'novalidate'}}) }}
{% if not form.vars.valid %}
<div class="global_form_errors">
{{ form_errors(form.name) }}
{{ form_errors(form.origin) }}
</div><br />
{% endif %}
<div>
{{ form_label(form.name) }}
{% if form.name.vars.errors|length != '' %}
{{ form_widget(form.name, { attr: {'class': 'field_red_border'} }) }}
{% else %}
{{ form_widget(form.name) }}
{% endif %}
</div>
<div>
{{ form_widget(form.button) }}
</div>
{{ form_end(form) }}
{% endblock %}

Customize the field template
You can apply a form template to your form, check this documentation at Form Theming chapter.
If you prefer theming the field directly in your template, check the gray box in this documentation at the Global Form Theming chapter.
Check this documentation for more form customization.
Pass the errors to the template
When you submit the form, your code will call this method $form->handleRequest($request); which will check if the user input properly the data.
Based on the documentation of the Form class you can get a list of errors by calling $form->getErrors(). The variable $form is an instance of the Form class and not the FormView class. You may want to enable error bubbling.
Now that you know how to get the errors you can pass them as a variable to your template.
