`childProcess.stdin.write()` is not working

[yxshv]

Details

So I am trying to communicate with the tsserver and am trying to write to the tsserver stdin

import { spawn } from 'child_process';

const { stdin: input, stdout: output }  = spawn('./node_modules/.bin/tsserver', []);

input.setDefaultEncoding('utf-8')

setTimeout(start, 5000)

output.pipe(process.stdout);

const textDocument = {
  uri: 'file:///Users/balkrishnaverma/Documents/yash/testum/src/index.ts',
  languageId: 'typescript',
  version: 2,
  text: `type JustATest  = {
  a: string,
  b: number
}
const abcd: Jus
`
};

async function start() {
  input.cork()
  input.write(JSON.stringify({
    seq: 0,
    type: "request",
    command: "open",
    arguments: {
      file: "/Users/balkrishnaverma/Documents/yash/testum/src/index.ts",
      fileContent: textDocument.text,
      projectRootPath: "/Users/balkrishnaverma/Documents/yash/testum",
    }
  }))
  input.uncork()
}

but its not actually writing for some reason? when i pipe process.stdin.pipe(input) and type json from my terminal it works?
