Warning: Undefined array key "license" in Drupal\Core\Asset\CssCollectionOptimizerLazy->optimizeGroup()

Created on 27 November 2023, 7 months ago

Updated 26 June 2024, 3 days ago

Problem/Motivation

After upgrading to Drupal 10.1 the logs are littered with these warnings:
Warning: Undefined array key "license" in Drupal\Core\Asset\CssCollectionOptimizerLazy->optimizeGroup()
Warning: Trying to access array offset on value of type null in Drupal\Core\Asset\CssCollectionOptimizerLazy->optimizeGroup()
Warning: Undefined array key "version" in Drupal\system\Controller\CssAssetController->generateHash()

Steps to reproduce

Install the module and create some menu icons
rebuild the cache and view any page with the menu icons
check the logs

Proposed resolution

The asset optimization pipeline seems to require license and version keys in the css definition. Thus they need to be set for the css file the simple menu icons generates.

Remaining tasks

create patch for adding "version" and "license" keys to css definition
