DF8203: Failed To Spawn PTY Session

Message

Failed to spawn PTY session for "{command}": {reason}

Cause

ctx.terminals.startPtySession() could not launch the requested command in a pseudo-terminal — for example the executable was not found, the working directory does not exist, or spawning was denied by the OS.

Fix

• Verify the command resolves on PATH (or pass an absolute path) and that cwd exists.
• Check the accompanying reason for the underlying spawn error.

Source

• packages/hub/src/node/host-terminals.ts — DevframeTerminalsHost.startPtySession() throws this when the initial zigpty spawn fails.
