DF8201: Terminal Session Not Registered

Message

Terminal session with id "{id}" not registered

Cause

ctx.terminals.update(patch) was called with an id for which no session has been registered.

Fix

• Use ctx.terminals.register(session) to add new sessions.
• Verify the id matches an existing session — common cause is updating after remove().

Source

• packages/hub/src/node/host-terminals.ts — DevframeTerminalHost.update() throws when sessions.has(patch.id) === false.
