Hey everyone,
I'm using the Crop module on my site and a few days ago I installed Imagick, I saw that Imagic implements an effect called "Posterize" but when I use it I can see a warning on the page "Undefined array key "type" in Drupal\crop\Entity\Crop::getCropFromImageStyleId()" and that happens because on Imagick the provider of it came as "imagick" and the Crop module consider as it should crop it.
On Entity/Crop.php::getCropFromImageStyleId instead of verifying that the provider is image to continue, let's check if it is not a crop.
Postponed: needs info
2.3
Code
I created a patch but I would like someone to review it, maybe it's important to keep it as image only
