curl parameters size limit

[rakotomandimby]

Hello,

With the below code, If the body is very big, I get a "value too large" error.
After having put logging everywhere, I found that the error is thrown at the curl.post line, when the body is past to plenary.curl.
I think that there is a size limit for the body, but I don't know how where is that limit set.
What is exactly the limit?

local curl = require('plenary.curl')
local query = {}

function query.askCallback(res, opts)
  -- Process res and opts
end

function query.ask(instruction, prompt, opts, api_key)
  local url = 'https://generativelanguage.googleapis.com'
  local path = '/v1beta/models/gemini-1.5-pro-latest:generateContent'
  curl.post(url .. path,
    {
      headers = {
        ['Content-type'] = 'application/json',
        ['x-goog-api-key'] = api_key
      },
      body = json.encode(
        {
          -- Big, very big body
        }),
      callback = function(res)
        vim.schedule(function() query.askCallback(res, opts) end)
      end
    })
end

return query
