that has not been attempted yet returns an empty page rather than a 404.

Endpoint: GET /notifications/{notification_id}/logs
Version: 2.0.0

  - `Auth` (unknown)
    apiKey in header X-Api-Key scopes: api:channel:read

## Path parameters:

  - `notification_id` (string, required)
    Unique identifier (UUID) of the notification.

## Query parameters:

  - `limit` (integer)
    Maximum number of items to return.

  - `page` (integer)
    Page number for pagination.

  - `sort_by` (string)
    Field to sort results by. Use `-` prefix for descending order.

## Response 200:

    Unique identifier (UUID).
    Example: 550e8400-e29b-41d4-a716-446655440000

  - `items.number` (integer, required)
    Authorization order within the notification. Manual sends can push it past ten.

  - `items.kind` (string, required)
    Why the attempt was authorized. Only automatic attempts consume the channel's max_attempts.
    Enum: "automatic", "manual", "test"

  - `items.status` (string, required)
    Evidence one attempt produced. `failed` means a proven pre-send failure or an explicit
rejection; `unknown` is neither, most often a lost response.
    Enum: "sending", "succeeded", "failed", "unknown"

  - `items.status_code` (any, required)
    HTTP status the destination answered with, or null when there was no response.

  - `items.error_code` (any, required)
    Typed cause of the failure, or null for a successful or still running attempt.

  - `items.error` (any, required)
    Short redacted diagnostic, or null when there is nothing to report.

  - `items.created_at` (string, required)
    Point in time in RFC 3339 format.
    Example: 2024-01-15T10:30:00Z

  - `items.completed_at` (any, required)
    Time the attempt finished, or null while it is still sending.

  - `items.duration_ms` (any, required)
    Measured duration of the attempt, or null when it was not measured.

  - `meta` (object, required)
    Pagination metadata returned on every list response. `page` and `limit` echo the values used to build this page (defaults are applied when the request omits them). `total` and `total_pages` reflect the full result set after any filters are applied.
    Example: {"limit":20,"page":1,"total":42,"total_pages":3}

  - `meta.limit` (integer, required)
    Page size used to build this response.

  - `meta.page` (integer, required)
    Index of the page returned, starting at 1.

  - `meta.total` (integer, required)
    Total number of items matching the request across all pages.

  - `meta.total_pages` (integer, required)
    Total number of pages available at the current `limit`.
