POST request with x-www-form-urlencoded is failing as Bad Request

[ssahillppatell]

Environment

bun: 1.1.38
node: 18.17.0
ofetch: 1.4.1

Reproduction

I have a simple api that accepts a name and return a json response.
Steps:

1. GO api to handle the request

package main

import (
	"encoding/json"
	"fmt"
	"log"
	"net/http"
)

func main() {
	http.HandleFunc("/hello", helloHandler)
	fmt.Println("Server is running on port 8080...")
	log.Fatal(http.ListenAndServe(":8080", nil))
}

func helloHandler(w http.ResponseWriter, r *http.Request) {
	if r.Method != http.MethodPost {
		http.Error(w, "Invalid request method", http.StatusMethodNotAllowed)
		return
	}

	err := r.ParseForm()
	if err != nil {
		http.Error(w, "Unable to parse form data", http.StatusBadRequest)
		return
	}

	name := r.FormValue("name")
	if name == "" {
		http.Error(w, "Name field is required", http.StatusBadRequest)
		return
	}

	response := map[string]string{"hello": name}

	w.Header().Set("Content-Type", "application/json")
	w.WriteHeader(http.StatusOK)

	json.NewEncoder(w).Encode(response)
}

2. Run via go run app.go
3. Try using the endpoint via

import { ofetch } from "ofetch";

const options = {
    method: 'POST',
    headers: {'Content-Type': 'application/x-www-form-urlencoded'},
    body: new URLSearchParams({
      name: 'abc'
    })
  };
  
  ofetch('http://localhost:8080/hello', options)
    .then(response => console.log(response))
    .catch(err => console.error(err));

It should error out.

Describe the bug

Form encoded post requests are not working as expected and erroring out(400).

Additional context

I tried using simple fetch and things were working as expected.

const options = {
    method: 'POST',
    headers: {'Content-Type': 'application/x-www-form-urlencoded'},
    body: new URLSearchParams({
      name: 'abc'
    })
  };
  
  fetch('http://localhost:8080/hello', options)
    .then(response => response.json())
    .then(response => console.log(response))
    .catch(err => console.error(err));

Even curl was working:

curl --request POST http://localhost:8080/hello --header 'Content-Type: application/x-www-form-urlencoded' --data name=abc

Logs

FetchError: [POST] "http://localhost:8080/hello": 400 Bad Request
