的JavaScript的MySQL - 類型錯誤：無法讀取空

Question

我試圖將結果輸出從選擇查詢日誌到控制檯的特性「嵌入」，但我得到以下幾點：

代碼：

connection.query("SELECT userID FROM inventories WHERE ?", invCheckedIDres, function(result) { 
    message.channel.send(result) 
}); 

錯誤：

C:\Users\apixe\Documents\GS Bot\node_modules\mysql\lib\protocol\Parser.js:79 
     throw err; // Rethrow non-MySQL errors 
     ^

TypeError: Cannot read property 'embed' of null

有我丟失的東西嗎？

您使用哪種模塊進行sql集成？

您沒有將其記錄到控制檯，您發送的信息不一致。查詢返回一個row/rows []對象，而message.send也接受一個字符串，而不是行。然而，我沒有在你提供的代碼中看到什麼是訪問「嵌入」這個代碼來自哪個行號？
