Why is JSON invalid?

Question

JavaScript

When trying to JSON.parse a string containing this JSON, an error occurs - https://pastebin.com/raw/xFf8JJEL (don't pay attention to the extra comma, by chance)
Validation in online validators also fails (you can copy it directly from the browser, I checked, the error is reproduced)
How to parse such lines? The original line is here, in the JSON-LD script tag - https://hiphopdx.com/news/id.53774/title.mc-eiht-s...

Answer 1

I don’t know how you pass the string to JSON.parse, but everything is fine with me

Answer 2

Obviously, the problem is a long space.
Change the encoding back and forth from CP-1251 to UTF-8 and back, it will most likely help.
