Warning: Undefined array key "#options" leads to TypeError: Drupal\Core\Form\OptGroup::flattenOptions():

Created on 22 December 2023, 11 months ago

Problem/Motivation

In cases where the options are empty, the following error is displayed:

TypeError: Drupal\Core\Form\OptGroup::flattenOptions(): Argument #1 ($array) must be of type array, null given, called in /var/www/docroot/modules/contrib/webform/src/Plugin/WebformElement/OptionsBase.php on line 222 in Drupal\Core\Form\OptGroup::flattenOptions() (line 23 of core/lib/Drupal/Core/Form/OptGroup.php).

Steps to reproduce

In my case, I'm using the Webform remote fields → module.

Install Drupal 10.2.0
Install Webform Remote Fields @2.0.0-alpha2
Enable the webform_remote_fields_examples Module
Go to "/admin/structure/webform". You will see 4 example forms
Go to "/form/remote-example", Select a user and select an option, then submit the form.
After this, go to the form results, and try to edit them. You'll see the error.

Proposed resolution

Ensure the value exists
Cover all cases on webform/src/Plugin/WebformElement/OptionsBase.php
Use null coalescing for better standardization

This issue is similar to the issue https://www.drupal.org/project/webform/issues/3324914 → , but the delivered solution does not cover all field types that has ['#option']. It missed checkboxes and radios.

Tested this on a D10.2 instance with PHP 8.1, I could see the error when editing the submit submission, applied the patch and I no longer see the issue:

This issue should be addressed by the Webform Remote Fields module and not the Webform module
