How to use the aiomultiprocess.types.ProxyException function in aiomultiprocess

async def results(self, tids: Sequence[TaskID]) -> Sequence[R]:
        """Wait for all tasks to complete, and return results, preserving order."""
        pending = set(tids)
        ready: Dict[TaskID, R] = {}

        while pending:
            for tid in pending.copy():
                if tid in self._results:
                    result, tb = self._results.pop(tid)
                    if tb is not None:
                        raise ProxyException(tb)
                    ready[tid] = result
                    pending.remove(tid)

            await asyncio.sleep(0.005)

        return [ready[tid] for tid in tids]
