Upgraded from Magento2.4.2pt1 to Magento2.4.4-pt1. Now reindexing from SSH I am getting error with reindexing catalog_product_attribute.
php -d memory_limit=2G bin/magento indexer:reindex catalog_product_attribute
ERROR
Product EAV index process error during indexation process:
Warning: Illegal offset type in /vendor/magento/module-catalog/Model/ResourceModel/Product/Indexer/Eav/Source.php on line 392.
I am not sure why I am getting this error or how to fix. Any help would be greatly appreciated. Thank you!
