Weird Duplicate Entry Error on Primary Key

I have a live project more than 5 years. And today i had a weird mistake. I wanted to update some of my products. And there exists a duplicate entry error.
I have no field as product_id in my products table. 12479 is id of my product. id is primary key and auto increment.
Firstly, i think it can be an laravel problem. I query mysql directly via phpmyadmin. It is same. But only for this product.
Here is my indexes.
Here is my table structure
I repaired my db from plesk also. Nothing change. Sometimes it works correctly.
Error from phpmyadmin
And the weirdest one is, this error occured when i update stock_quantity field. I can update other fields without problems.
I noticed a mysql bug while searching MySQL Bug: https://bugs.mysql.com/bug.php?id=68360
What should i do ?
解决方案
I solved problem. (Mysql Error Handling is not good. Descriptions must describe the situation better)
I had a trigger for stock_quantity. If a product sold out and get in stock again. I'm sending mail to customers. In that table(products_notify) product_id is unique. And the products which has ids on products_notify fails.
Thanks @Rodrane
