elicitation channel closed

Error message

elicitation channel closed

What it means

Returned when, after successfully sending an ElicitationRequest, the oneshot response channel is closed before the answer arrives (the UI side dropped the request). No elicitation response can ever be produced, so the operation fails with this sentinel.

Solutions

1. Abort the tool call awaiting elicitation; the response will never arrive
2. Re-issue the request to trigger a fresh elicitation prompt
3. Investigate why the requesting UI dropped (thread cancelled, window closed)
