Unable to use zValidator for query with POST requests

[kolyasapphire]

Hey! First of all thank you so much for your Hono and the Node.js adapter work - they are awesome!

I've noticed that this code works fine with just Hono on Vercel inside Next.js:

import { Hono } from 'hono'
import { zValidator } from '@hono/zod-validator'
import { handle } from 'hono/vercel'
import * as z from 'zod'

const schema = z.object({
  test: z.string(),
})

const app = new Hono().post('*', zValidator('query', schema), (c) =>
  c.text('test')
)

export default handle(app)

export const runtime = 'edge'

But when using the honojs/node-server like so:

import { Hono } from 'hono'
import { zValidator } from '@hono/zod-validator'
import { handle } from '@hono/node-server/vercel'
import * as z from 'zod'

const schema = z.object({
  test: z.string(),
})

const app = new Hono().post('*', zValidator('query', schema), (c) =>
  c.text('test')
)

export default handle(app)

I am getting:

Without zValidator it also works as expected.

Hi @kolyasapphire,

I've tried running the code, but it seems to work fine on my environment. Therefore, the issue might be related to package dependencies. Could you create a GitHub project to reproduce the issue? Once you do that, I can investigate it.

Hey @yusukebe,

Absolutely, here you go:

Thanks for looking into this!

@kolyasapphire

Thanks! You might fix this issue with adding the following:

export const config = {
  api: {
    bodyParser: false
  }
}

This is related to #84

import requests

with requests.session() as session:

url = 'https://register.fdsinstitut.com/ext/index.php'

headers = {}
cookies = {}
donnees = {}

reponse = session.post(url, headers=headers, cookies=cookies, data=donnees)

print(reponse.text)

[herrAlison]

dieses programm löuft nicht richtig ,

Thanks @yusukebe! Works as expected now
