DigitalOcean Functions: How to differentiate query params from body params?

I made a request with the following arguments:

• Path: /test?potato=true
• Body: { "banana": true }

In the event, I receive:

{
  "banana": true,
  "potato": "true",
  "__ow_method": "post",
  "__ow_headers": {
    "accept": "*/*",
    "accept-encoding": "gzip",
    "cdn-loop": "cloudflare",
    "cf-connecting-ip": "xx",
    "cf-ipcountry": "BR",
    "cf-ray": "xx",
    "cf-visitor": "{\"scheme\":\"https\"}",
    "content-type": "application/json",
    "host": "ccontroller",
    "user-agent": "insomnia/2022.4.2",
    "x-custom": "okay",
    "x-forwarded-for": "xx",
    "x-forwarded-proto": "https",
    "x-request-id": "xx"
  },
  "__ow_path": ""
}

My question is: How do I differentiate a query param from a body param?

This way, it’s impossible to know if it’s a query param or a body param, except when the body is formatted in base64, in which case I get the body inside __ow_body.

Context: I’m a maintainer of serverless-adapter which integrates serverless clouds with any nodejs framework, I want to add support for Digital Ocean Functions to deploy apps like nestjs, trpc, etc.
