DF8200: Terminal Session Already Registered

Message

Terminal session with id "{id}" already registered

Cause

ctx.terminals.register(session) or ctx.terminals.startChildProcess(opts, terminal) was called with an id that another session already owns. Terminal ids are unique per hub context.

Fix

• Pick a different session id (namespace under your tool: my-tool:build-server, my-tool:tests, …).
• If you want to reuse an existing session's slot, ctx.terminals.remove(session) first.

Source

• packages/hub/src/node/host-terminals.ts — DevframeTerminalsHost.register() and startChildProcess() throw when the id is already taken.
