            time_range (Union[dict, ~google.cloud.errorreporting_v1beta1.types.QueryTimeRange]): [Optional] List data for the given time range. If not set a default time

                the beginning of this time range. Only ErrorGroupStats with a non-zero

                If a dict is provided, it must be of the same form as the protobuf
                message :class:`~google.cloud.errorreporting_v1beta1.types.QueryTimeRange`
            group_id (list[str]): [Optional] List all ErrorGroupStats with these IDs.

            alignment_time (Union[dict, ~google.cloud.errorreporting_v1beta1.types.Timestamp]): [Optional] Time where the timed counts shall be aligned if rounded
                alignment is chosen. Default is 00:00 UTC.

            page_size (int): The maximum number of resources contained in the
                underlying API response. If page streaming is performed per-
                resource, this parameter does not affect the return value. If page
                streaming is performed per-page, this determines the maximum number
                of resources in a page.
            retry (Optional[google.api_core.retry.Retry]):  A retry object used
                to retry requests. If ``None`` is specified, requests will not
                be retried.
            timeout (Optional[float]): The amount of time, in seconds, to wait
                for the request to complete. Note that if ``retry`` is
                specified, the timeout applies to each individual attempt.
