tty: process.stdin.write() throws #22905

Closed

Description

@mcollina
  • Version: 10 (since libuv 1.20)
  • Platform: all
  • Subsystem: tty, net

This behavior is a regression caused by libuv (see libuv/libuv#1936 and #21654).

Currently:

process.stdin.write('hello')

Throws

events.js:167
      throw er; // Unhandled 'error' event
      ^

Is this error acceptable/understandable, or should we do a custom error like #21654?
