    Lists the specified groups.

    Args:
      projectName: string, The resource name of the Google Cloud Platform project. Written as
    `projects/` plus the
    [Google Cloud Platform project ID](https://support.google.com/cloud/answer/6158840).
    Required. Example: `projects/my-project-123`. (required)
      alignmentTime: string, Time where the timed counts shall be aligned if rounded alignment
    is chosen. Default is 00:00 UTC.
      pageSize: integer, The maximum number of results to return per response.
    Default is 20.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format
      alignment: string, The alignment of the timed counts to be returned.
    Default is `ALIGNMENT_EQUAL_AT_END`.
      timedCountDuration: string, The preferred duration for a single returned `TimedCount`.
    If not set, no timed counts are returned.
      timeRange_period: string, Restricts the query to the specified time range.
      pageToken: string, A `next_page_token` provided by a previous response. To view additional
    results, pass this token along with the identical query parameters as the
    first request.
      serviceFilter_version: string, The exact value to match against
    [`ServiceContext.version`](/error-reporting/reference/rest/v1beta1/ServiceContext#FIELDS.version).
      serviceFilter_service: string, The exact value to match against
    [`ServiceContext.service`](/error-reporting/reference/rest/v1beta1/ServiceContext#FIELDS.service).
      groupId: string, List all `ErrorGroupStats` with these IDs.
    If not specified, all error group stats with a non-zero error count
    for the given selection criteria are returned. (repeated)
      order: string, The sort order in which the results are returned.
    Default is `COUNT_DESC`.
