Error message

turn canceled

What it means

Sentinel default for a turn that terminated with TurnTerminalStatus::Canceled and no error detail from the runtime. The turn was explicitly canceled (as opposed to failing), and the empty error field means the cancellation reason must come from the caller or logs.

Solutions

1. Confirm whether you or a client intentionally canceled the turn; if so this is expected
2. If unintended, find which component sent the cancel and stop it
3. Re-issue the turn once the cancellation source is resolved
4. Check runtime logs for the cancellation origin
