+1 to patch in #9 🐛 Fatal error: Declaration of Drupal\lightning_core\ConfigEntityDescriptionTrait::getDescription() must be compatible with Drupal\Core\Entity\EntityDisplayModeBase::getDescription(): string RTBC .

We came across the same error after upgrading to Drupal core 10.2.
The patch provided by #9 fixed the issue.
Please add this to a new stable release.

After upgrading to Drupal core 10.2 we also came across the same error.
Patch #9 🐛 Fatal error: Declaration of Drupal\lightning_core\ConfigEntityDescriptionTrait::getDescription() must be compatible with Drupal\Core\Entity\EntityDisplayModeBase::getDescription(): string RTBC fixed the issue.

I am also facing the same issue after upgrade Drupal 10.2.2 with PHP 8.2 and tried this patch #9, the issue fixed now and site was working fine.

The patch in #9 worked for me as well, upgrading to 10.2 with PHP 8.1. Thanks!

Created MR for quick merge.

I ran into this issue with the `lightning_core` module following an upgrade of Drupal from version 10.1.8 to 10.3.1. Unfortunately, patch number 9 was ineffective for me because I needed to fix both functions in the `ConfigEntityDescriptionTrait.php` file. The patch provided below resolved the problem and I will create a Merge Request to make it permanent.

@drupalam, sorry to be weighing in on this late in the game, but we have in core/lib/Drupal/Core/Entity/EntityDescriptionInterface.php the following:

 /**
     * Sets the entity description.
     *
     * @param string $description
     *   The entity description.
     *
     * @return $this
     */
    public function setDescription($description);

It seems that setDescription() returns $this (an EntityDescriptionInterface), so trying to coerce the result to a string as in #21 is going to give a type error, unless I'm missing something.

@puregin was correct! Here’s a solution to this

Hi - just a double confirmation note from my side, that the 2 comments above are correct. #27 is the right one, the #21 results with an error when saving new View Mode.
