Using json in conjunction with pug with Grunt builder?

Question

JSON

Everywhere I find information on this issue, but with answers: how to configure gulp so that pug eats data files. But I need Grunt settings, and I can't even find such articles. Grant is dead? Okay, this is a rhetorical question.
1) People, does anyone know if it is possible to set up a bunch of json to pug in Grant? If so, how?
2) I tried to register in the config

data: {
        jobs: grunt.file.readJSON('src/etvm/facts.json')
      }

But it gave an error
Unexpected token c in JSON at position 2
What could be the problem? What am I doing wrong? What is this symbol c ?
3) And besides, I decided to try to do without files and write data to a variable directly in the pug file.

- var facts = [
    {
      "question": "текст",
      "answer": "вот такой вот текст",
      "answer_two": "большой текст"
    },
    {...}
]

each fact in facts
  h3.facts__title !{fact.question}

But in the console, grunt gives an error:

>>     1| - var facts = [
>>  > 2|     {
>> ---------^
unexpected text "{

What could be the problem? What am I doing wrong? Here , a person succeeds in everything, but I don’t :(

Answer 1

Grant is dead?

Yep. And how long.
Invalid JSON, show file. Or, perhaps, an error in the path to the file, xs how does grunt.file.readJSON work there. Try './src/etvm/facts.json'.
pug does not understand this, the whole expression - varmust go in one line.
You are on the right track, only something with reading json did not work for you.
