Crawl Error Type for /videos

For the /videos endpoint, in addition to using HTTP status codes to indicate errors, we also use a status field to display specific error information for each video. This design facilitates more precise error management when retrieving multiple URLs. 
{
  "results": [
    {
      "data": {...},
      "status": {
        "url": "https://www.youtube.com/watch?v=xxx",
        "status": "Success"
      }
    },
    {
      "status": {
        "url": "https://www.youtube.com/watch?v=xxx",
        "status": "Fail",
        "error": {
          "type": "CRAWL_NOT_FOUND"
        }
      }
    }
  ]
}
