Error getting json?

Question

JavaScript

I request JSON data via Ajax, nothing special, everything works.
But this error pops up in the console:

What does this mean? JSON is absolutely correct, this is confirmed by:
- ​​Code performance (everything is parsed normally) -
Online validator -
I myself
Just in case, here is the content of test.json:

{
  "data"   : [
    {
      "id" : 1,
      "content" : "<p>Тестовый текст</p>",
      "title" : "Тестовое название",
      "rating" : 222,
      "info" : {
        "comments" : 42,
        "views" : 448,
        "spawnDate" : "12.12.2015"
      },
      "author" : {
        "avatar" : "none.png",
        "rating" : 23,
        "name" : "Капитан аноним"
      },
      "tags" : [
        "Тег1", "Тег2", "Тег3"
      ]
    }
  ],
  "status" : "OK",
  "count"  : 1
}

Answer 1

Is the encoding of test.json okay?

Answer 2

In fact, for Firefox, such an error is incorrect. It will not give such an error. See how your JSON is unpacked.
