Check if a field is empty inside a twig paragraph template

Question

I know how to check if a field is empty in a twig template (example node--lorem.html.twig):

{% if node.field_lorem.value is not empty %} <p>not empty</p> {% else %} <p>empty</p> {% endif %}

I would like to check if a field is not empty inside a paragraph twig template (example paragraph--lorem.html.twig). But this doesn't work :

{% if content.field_lorem.value is not empty %}

or

{% if node.field_lorem.value is not empty %}

I can display this field value like this :

{{ content.field_lorem }}

Why the downvote ? I could improve the question if I know why. — Sébastien Gicquel

How do I get the raw field value in a twig template? - Replace node with paragraph — Hudri

@Hudri No, I just want to check if a paragraph field is empty or not. I don't want to get the raw value. — Sébastien Gicquel

{% if paragraph.field_lorem.value %}, not node. Not content. content contains only fields that have been added to the display of your entity. — norman.lol

To check if a field is empty use ItemList::isEmpty

Node

{% if node.field_example.isempty %} <p>Field is empty</p> {% endif %}

Paragraph

{% if paragraph.field_example.isempty %} <p>Field is empty</p> {% endif %}
