Retrieves the next page of results.

### Method Details

`list(filterSetName=None, 123, pageToken=None, pageSize=None, x__xgafv=None)`

    List all reasons that caused a bid request not to be sent for an
    impression, with the number of bid requests not sent for each reason.

    Args:
      filterSetName: string, Name of the filter set that should be applied to the requested metrics.
    For example:

    - For a bidder-level filter set for bidder 123:
      `bidders/123/filterSets/abc`

    - For an account-level filter set for the buyer account representing bidder
      123: `bidders/123/accounts/123/filterSets/abc`

    - For an account-level filter set for the child seat buyer account 456
      whose bidder is 123: `bidders/123/accounts/456/filterSets/abc` (required)
      pageToken: string, A token identifying a page of results the server should return.
    Typically, this is the value of
    ListFilteredBidRequestsResponse.nextPageToken
    returned from the previous call to the filteredBidRequests.list
    method.
      pageSize: integer, Requested page size. The server may return fewer results than requested.
    If unspecified, the server will pick an appropriate default.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:
