Why does BX.setJSList is not a function error occur in Google seacrh console?

Question

1C-Bitrix

When checking the site in the Google seacrh console, when checking the optimization for mobile, the following error appears in the messages from the console:
Uncaught TypeError: BX.setJSList is not a function

At the same time, there is nothing like this in the browser, neither for PC nor mobile.

CJSCore::Init() is enabled in the header.

What can be done about it?
And how can you reproduce the actions of googlebot'a to repeat the error?

Answer 1

Googlebot doesn't load core.js, so it doesn't know BX.setJSList either.
Here is an article that I think gives an explanation of this situation.
