After upgrade prestashop to 1.7.8.2 ,when I try to add an image to the product, an error appears, which is in the screenshot but only in this product.

Is there anyone have any idea of this error please?

Solution : 

I duplicate this product with the same reference; if this product has already been purchased from a customer, you can leave this one but no longer online (invisible) for a few days, then delete it if you want and make the new one visible to customers. , the new product works well.

PS: I say that the problem is on a single product and this solution works well for me. You can do your tests.
