Custom Paragraph Twig Templates Break Mercury Editor Saving and Controls

Created on 30 July 2025, 2 months ago

Problem/Motivation

I am using custom Paragraph and Node Twig templates to restrict my markup to email-friendly only HTML. However, when I assign a Paragraph type with a custom Twig template to the Mercury Editor and add it to my node the Mercury Editor controls are missing in edit mode and when I save the node the Paragraph is not saved.

Steps to reproduce

Create a custom template for a Paragraph type (e.g., paragraph--hero.html.twig)
Template includes {{ content }} or {{ content|without('field_hero_title') }}
Add this Paragraph in Mercury Editor UI on a node
Paragraph is not saved and Mercury Editor controls do not display

Tested with:

Mercury Editor: 2.2.4
Layout Paragraphs: 2.1.1
Paragraphs: 1.19.0
Mercury Layouts dev-2.0.x

Notes:

Removing the custom template restores saving and Mercury controls
No PHP or JS errors in logs
Happens on multiple Paragraph types

Please let me know what other information I may provide, or if my use-case is not supported. Thank you.

Hi,

I have resolved my issue. I needed to add the {{ attributes }} variable to my Twig templates.

This issue may be closed.

Thanks,
