nodejsにroutes.jsファイルを定義しました。すべてのルートは「UPDATEAUTH」ルートを除いて完全に動作しています。その場合、ヘッダーはすでに送信されています。エラーが発生しています。 router.post("/updateauth",function(request,response){...});ヘッダーはすでにnode.jsエラーを送信しました
エラーは、私がそれにコールバックを添付することができるように解決策を見つけたいresponse.json(found);
で発生> - それは最後にあります。

どうすれば解決できますか？データがすべてのルートを通って別々に送信されるようにする必要があります。 –
@IshanSharma console.log出力は何回も出力されますか？ –
はい、私はそれを使ってユーザーの活動を追跡しています。 –
