third-party module – Can not verify the quantity requested for products without support problem for source articles on 2.3.1

I have a custom module installed. A module that adds a product type to display a product. In the product configuration, it offers other sets of parameters (minimum price, maximum price and total price target to be defined as a success transaction) that does not align with the quantity parameter. It does not require the default quantity

It's the mistake when the user clicks Add to Cart
Error encountered

I believe that one of these settings (which is the amount based on the error display) is somehow related and processed when the user places the order is useless
find the problem

And these are the parameters that the module has provided to work on the backend
Module parameter

I hope that someone who has experienced a similar situation would like to share some ideas on solving this problem.
