Hi,
After upgraded to Drupal 9 (https://ams02.space/), we keep noticing error messages like this one:
Notice : Trying to access array offset on value of type bool in Drupal\cern_components\TwigExtension\CernComponentsTwigExtension::renderThis() (line 632 of /app/web/modules/custom/cern-components/src/TwigExtension/CernComponentsTwigExtension.php )
The website looks okay, but the error constantly shows up in the admin portal.
Could you help me to check the source of the error message?
Thank you!
