我正在使用以下内容：
mongodb 7.0 in a vm（ubuntu no container）nodejs 18+ mongoose 7.5.0 kubernetes 1.28.3
当我在kubernetes容器中运行应用程序时，应用程序能够连接和查询db，db位于k8s外部，但它在集群中的每个应用程序中的每个查询中都返回一个空集。
下面是连接代码，它对所有应用程序都是相同的。

// -------  Start Mongo connection ---------------------------
mongoose.set("strictQuery", false);
mongoose.set("bufferCommands", true);
let result = true;

const options = {
  useNewUrlParser: true,
  useUnifiedTopology: true,
  autoIndex: true,
  serverSelectionTimeoutMS: 5000, // Keep trying to send operations for 5 seconds
  family: 4, // Use IPv4, skip trying IPv6.
};
mongoose.set("debug", true);

const mongo_url = `${process.env.MONGO_connectionType}://${process.env.MONGO_url}/${process.env.MONGO_dbname}?replicaSet=${process.env.MONGO_replicaSet}&readPreference=${process.env.MONGO_readPreference}`;

mongoose.connect(mongo_url, options).catch((e) => {
  errorLog("Index", "app-listen", `Mongoose failed to connect to DO with error ${e.message}`, false, "error");
  result = false;
});

mongoose.connection.once("open", () => console.log(`Connected to Mongoose on DO using ${process.env.MONGO_dbName}`));
// listen for errors after the initial connection.
mongoose.connection.on("error", (error) => {
  console.error(error);
  if (error.name === "MongooseServerSelectionError") {
    console.log(error.reason.servers);
  }
  result = false;
});
mongoose.connection.on("disconnect", (error) => {
  console.error(error);
  result = false;
});
// --------------- End Mongoose Connection -------------------

字符串
下面是连接和查询的控制台输出

型
代码不会发出任何类型的错误，只是返回一个空的结果。我已经在vscode debug中运行了相同的代码，访问相同的数据库，一切都按预期工作。是的，数据库中有数据要返回。我不知道如何调试这个。任何关于在哪里查找的建议都将是有帮助的。
谢谢
