Request Body containing a number close to Number.MAX_SAFE_INTEGER has the number transformed to a string

[vypxl]

I have checked the following:

• I use the newest version of bruno.
• I've searched existing issues and found nothing related to my issue.

Describe the bug

Creating a request with a body like this:

{
  "max": 9007199254740991
}

Sends this request:

> GET /x
> X-Tunnel-Auth-Token:
> x-tunnel-workflow: api
> content-type: application/json
> data {"max":"9007199254740980"}

Note the quotes around the number on the last line.

I consider this a bug. It is not documented behavior, and causes non-obvious errors. The api I was testing reported an invalid request error, and it took me hours to find out that Bruno was the culprit, because it changed the datatype of the number to string.

I investigated why this is happening (theory):

here json-bigint is used to parse the request body and pass it to axios. However, axios does not correctly serialize it back to the same string as the input. I believe JSONBig.stringify must be used to ensure correct conversion.

Alternatively, just giving axios the input string without ever parsing it might be an option.

Note: the req.body object in the script context already has the field as a string..
