How to reproduce validation behavior on mobile frendly?

Question

Google

When checking the site through the https://search.google.com/test/mobile-friendly test , I
see errors in messages from the JavaScript console :
$ is not a function
vue is not a function
, etc.

At the same time, on the same pages in normal mode on desktop and mobile, everything is ok.
Errors are observed only in the search console.

What is the feature of this test? Maybe he runs the site in an iframe?
How can you reproduce the behavior of this test?
