parsererror

when I have a product in the cart and go to payment, at the bottom I have suggested products that have a lower price and when I click to add them to the order, the “parsererror” error occurs

Hi,
the plugin is still running, you need to add a product to the cart and the proposed products will appear at the very bottom of the order.

I am sending screenshots of what these proposed products look like: https://imgur.com/a/jXMiZ7n
