[bonk1t]

The main fix: NoneType has no attribute 'id' (self._run.id):

        try:
            actual_thread_id = thread_id or self.id
            actual_run_id = run_id or (self._run.id if self._run else None)

            if not actual_run_id:
                return  # Can't cancel without a run ID

            self._run = self.client.beta.threads.runs.cancel(
                thread_id=actual_thread_id, run_id=actual_run_id
            )
        except BadRequestError as e:
            if "Cannot cancel run with status" in e.message:
                self._run = self.client.beta.threads.runs.poll(
                    thread_id=actual_thread_id,
                    run_id=actual_run_id,
                    poll_interval_ms=500,
                )
