Error related to json request parsing

[Kolhun]

Hello everyone, I have a question, I'm using json::parsing to download information and get the following error

The JSON itself for parsing looks like this

{
    "from": "products",
    "limit": "",
    "method": "update",
    "order": "",
    "vars": {
        "price": "80",
        "items": "3"
    },
    "where": "id IN('44852')"
}

At the same time, JSON is correct, and the response JSON (the whole thing is involved in sending the request body to the server) and always looks like this

{
    "status": "succes"
}

What could be the reason for such an error?

The what() message of the parse error exception should give you an idication of the byte where parsing fails.
