DF8202: Terminal Session Does Not Accept Input

Message

Terminal session "{id}" does not accept input

Cause

hub:terminals:write or hub:terminals:resize was called for a session that is output-only. Sessions started with ctx.terminals.startChildProcess() are pipe-backed and read-only; only PTY sessions from ctx.terminals.startPtySession() accept keystrokes and resize.

Fix

• Spawn the session via ctx.terminals.startPtySession(executeOptions, terminal) to get an interactive, writable PTY.
• If you only need to stream output, keep using startChildProcess() and don't wire input to it.

Source

• packages/hub/src/node/rpc-builtins.ts — the hub:terminals:write / hub:terminals:resize handlers throw this when the resolved session has no write handle.
