Sharepoint newly created document library can not respond graph api for long time.

I'm developing share point upload feature using graph api.

But newly create document library path can't respond graph query for some hours.

After passing some hours, I can get response using same query.

Why it takes time to using graph query for newly created library path?

1. Log with MS-signing.
2. In share point site that i can access. create new document library
   1. create new document library "syhtest" url : https://hp.sharepoint.com/teams/HPPK-TEST4/syhtest/Forms/AllItems.aspx
3. I https://developer.microsoft.com/en-us/graph/graph-explorer site.
   1. execute graph api query to new library path.
   2. post : https://graph.microsoft.com/v1.0/search/query

      {
          "requests": [
              {
                  "entityTypes": [
                      "drive"
                  ],
                  "query": {
                      "queryString": "teams/HPPK-TEST4/syhtest AND Path:\"https://hp.sharepoint.com/teams/HPPK-TEST4/syhtest\""
                  },
                  "fields": [
                      "id",
                      "webUrl",
                      "parentReference"
                  ]
              }
          ]
      }
   

   no hit response

      {
          "value": [
              {
                  "searchTerms": [
                      "teams/HPPK-TEST4/syhtest"
                  ],
                  "hitsContainers": [
                      {
                          "total": 0,
                          "moreResultsAvailable": false
                      }
                  ]
              }
          ],
          "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#Collection(microsoft.graph.searchResponse)"
      }
   

4. After passing some hours. i can get hit response using same query.
