Data is not sent using axios to backend in react and Unsupported protocol localhost: axoos is thrown

Question

I am using express js as backend and also have added proxy of backend in the package.json of react js. Before it used to throw an error with fetch method and moved to the axios method to prevent that. The data is in json format and completely working after copy pasting on postman to check backend.

import React ,{useState} from 'react'
import './contact.css'
import axios from "axios"


const Contact = (e) => {
    const [email, setEmail] = useState('')
    const [description,setDescription]=useState('');
    const[message,setMessage]=useState('')

const [name ,setName] = useState('')


const url='localhost:5000/api/contact'
    const contactClick=async (e)=>{
      const subject="contacting"
        e.preventDefault();
      const formData={
        name:name,
        email:email,
        subject:subject,
        description:description
      }

      console.log(JSON.stringify(formData));
      axios.post(url, JSON.stringify(formData))
   .then(res => setMessage('email sent'))
   .catch(err => {setMessage('Unable to sent email ')
  return console.log(err)})

    };
    
  return (
    <>
    <div className='form__container' >
    <form onSubmit={contactClick} className='contact__form'>
    {message}

        <input type="email" placeholder='Email' value={email} required onChange={(e)=>setEmail(e.target.value) 
} />


        <input type="text"  placeholder='name' value={name} required onChange={e=>setName(e.target.value)} />
        <input type="textarea" placeholder='Description' className='text-area' value={description} onChange={(e)=>setDescription(e.target.value)}/>
        <input type="submit" title="Submit" />

    </form>
    </div>
    </>
  )
}

export default Contact

I think axios.post() takes data as object not string as mentioned here in the docs.

replace it with axios.post(url, formData) without stringifying it.

https://axios-http.com/docs/post_example

But the resulted data from JSON.stringify(formData) is '{the data}'
