Product has incorrect parameters! Missing field

Good Evening,

I am using plugin to output a final product price based on the product dimension. Everything works fine during the process of calculating the final price.

But when I put more than one product in my cart, I get an error when completing the order related to one of the fields I have added to the products. e.g. Product has incorrect parameters! Missing field [Name] in product #809.

A parameter which, however, I had completed before adding the product to the basket.

I should note that when I put only one product, the order may be completed normally.

Thanks in advance.
