Elysia doesn't parse html body content for GET requests

[maxshay]

What is the type of issue?

Documentation is incorrect, Documentation is confusing, Example code is not working

What is the issue?

Using the example code found at https://elysiajs.com/patterns/mvc.html#service:

import { Elysia, t } from "elysia";

abstract class Service {
  static fibo(number: number): number {
    if (number < 2) return number;

    return Service.fibo(number - 1) + Service.fibo(number - 2);
  }
}

const app = new Elysia()
  .get(
    "/fibo",
    ({ body }) => {
      console.log(body);
      return Service.fibo(body);
    },
    {
      body: t.Numeric(),
    }
  )
  .listen(3000);

And running with postman:

I get a validation error:

{
  "type": "validation",
  "on": "body",
  "property": "root",
  "message": "Expected union value",
  "expected": 0,
  "errors": [
    {
      "type": 62,
      "schema": {
        "anyOf": [
          {
            "format": "numeric",
            "default": 0,
            "type": "string"
          },
          {
            "type": "number"
          }
        ]
      },
      "path": "",
      "message": "Expected union value"
    }
  ]
}

Removing the validation check I log out undefined when printing: console.log(body); as well as get a {"name":"RangeError","message":"Maximum call stack size exceeded."} response.

I assume according to best practices you shouldn't send HTTP body with GET requests. Do the docs need to be updated with .post(...) or is there a way to allow Elysia to parse GET body content?
