每次我根據這個索引加載儀表板時，這個錯誤不斷彈出
我的可視化效果仍然很好，資料仍在出現，我以前從未遇到過這個錯誤。關于如何解決此問題的任何想法？
這是錯誤彈出視窗的回應：

uj5u.com熱心網友回復：
您有一個檔案，其中的欄位沒有user.followers_count. 您的腳本欄位根本沒有檢查它，因此當它無法回傳任何值時會出錯。這A document doesn't have a value for a field就是錯誤中所說的
試試這個，如果該欄位為空，它將回傳一個零，基本上是創建一個默認值；
if (doc['user.followers_count'].size() == 0) { return "0" } else { return doc['user.followers_count'].value > 9999 ? 1 : 0 }
