"PriceSystem" Error Python *URGENT*

Good morning everyone, I have a script in Python created to do webscraping from a site to my e-commerce in shopify, until two days ago everything worked perfectly, then it started to give me this error that I attach in the image, I also attach part of the code of the .py application, can anyone tell me if Shopify has changed some parameter with some update ?

I didn’t make the script, I’m not a programmer but if the change is small I can try to make it.

I would like to point out that the script has always worked and loaded the products with price and everything, the site I get the products from is HEO.COM.

Thanks
