Adding text content through HTTP

Hi folks,

I’m trying to use the IPFS endpoint for adding/pinning content, but keep running in to the same error:
'invalid path "hello world": selected encoding not supported'

Below is my typescript code

import FormData from 'form-data';

async function test() {
  const auth = Buffer.from('projectId:projectSecret').toString('base64');

  const formData = new FormData();
  formData.append('test', Buffer.from('hello world'));

  const resp = await fetch('https://ipfs.infura.io:5001/api/v0/pin/add', {
    method: 'post',
    headers: { authorization: `Basic ` + auth, ...formData.getHeaders() },
    body: formData,
  });

  console.log(resp);
}

test();
