I am currently facing a problem with the below error and was hoping if someone could help.
Notice: Undefined index: quantity in /public_html/Magento/vendor/magento/module-inventory-sales/Model/IsProductSalableCondition/IsSalableWithReservationsCondition.php on line 87
I have found solutions to other Undefined Index problems but not to mine.
This error happens on the product page when I edit certain products. Please note it only happens to a few products.
I've tried to go into the attribute settings, re-saving and then reindexing but this has not worked. I've had a look into the database and couldn't find anything that stands out as wrong.
Any helps is appreciated, I am also getting a "Something went wrong with processing the default view and we have restored the filter to its original state." error when searching for some products but I believe these problems are related.
