Error parsing JSON: Syntax error

Hi, I'm working with Xano and Bubble. There's a table for products in Xano and I want to create new products in this table through an API. I checked the Documentation (Swagger) and copied the JSON to add a new product.

Then, I created the API in Bubble this way:
[API Configuration.png][API Dynamic Values.png]
But when I try to initialize the call in Bubble, it returns this error:
[API Response Error.png]
I've never seen this error before. Can anyone help me with this? Any help is welcome.
