Why products are not displayed in Bitrix?

Question

JavaScript

When the catalog goes to the parent category, products are not displayed, it says "No results were found for your request.".
Although the goods should be there, and no search filters are set.
The console shows the following errors:
Uncaught SyntaxError: Unexpected token ,
kernel_main.js:353 BX.debug: Arguments(2)0: "BX.ready error: "1: ReferenceError: filterParameters is not defined

Answer 1

I would first look at this kernel_main.js:353 error. (file and line).
Also looked what there is a request for an output of the list of goods. You can look in debug mode. This is the first thing I would do.
And so it is very difficult to say what the reason is without seeing at least the site itself.
