winston.transports.MongoDB pushes empty root path "/"

[azwinlam]

When using normal winston to push logs to file, only routes (non root only, ( / ) ) gets saved. On mongodbwinston, I am receiving many lines of root routes with no meta, no data.

Anyone have similar problems?

{'method': 'GET', 'path': '/restaurant', 'userId': '60f91de2aacd8b54faa7b662', 'username': 'admin', 'query': {}}
{'method': 'GET', 'path': '/', 'userId': None, 'username': None, 'query': {}} <==== This being logged unneccesarily
{'method': 'GET', 'path': '/', 'userId': None, 'username': None, 'query': {}}
{'method': 'GET', 'path': '/', 'userId': None, 'username': None, 'query': {}}
{'method': 'GET', 'path': '/', 'userId': None, 'username': None, 'query': {}}
{'method': 'GET', 'path': '/restaurant', 'userId': '60f91de2aacd8b54faa7b662', 'username': 'admin', 'query': {}}

Hi @azwinlam!

Can you, please, share your Winston config and, ideally, a minimal reproducible example?

Thanks! Edit for formatting

const dotenv = require("dotenv").config();
require("winston-mongodb");

const {
  combine,
  timestamp,
  label,
  printf,
  prettyPrint,
  colorize,
  json,
  align,
} = winston.format;
const myFormat = printf(({ level, message, label, timestamp }) => {
  return `${timestamp} [${label}] ${level}: ${message}`;
});

const mongoURL = process.env.MONGO_URL || "failed";

const allLogger = winston.createLogger({
  level: "info",
  format: combine(json(), label({ label: "cob-rn6" }), timestamp()),
  transports: [
    new winston.transports.MongoDB({
      level: "info",
      //mongo database connection link
      db: mongoURL,
      options: {
        useNewUrlParser: true,
        useUnifiedTopology: true,
      },
      // A collection to save json formatted logs
      collection: "server_logs",
      format: combine(json(), label({ label: "cob-rn6" }), timestamp()),
    }),
  ],
});

if (process.env.NODE_ENV !== "production") {
  allLogger.add(
    new winston.transports.Console({
      format: combine(json(), label({ label: "cob-rn6" }), timestamp()),
    })
  );
  allLogger.add(
    new winston.transports.File({
      filename: "./log/error.log",
      level: "error",
      format: combine(json(), label({ label: "cob-rn6" }), timestamp()),
    })
  ),
    allLogger.add(
      new winston.transports.File({
        filename: "./log/combined.log",
        format: combine(json(), label({ label: "cob-rn6" }), timestamp()),
      })
    );
}

module.exports = allLogger;

  useNewUrlParser: true,
  useCreateIndex: true,
  useUnifiedTopology: true,
});

const app = express();
app.disable("x-powered-by");
app.use(express.json());

app.use((req, res, done) => {
  const meta = {
    method: req.method,
    path: req.path,
    userId: req.header("User"),
    username: req.header("Username"),
    query: req.query,
  };
  allLogger.info("CombinedLog", { metadata: meta });
  // console.log(req.path);
  done();
});```

Let me try to explain the problem again.

When using normal winston logging transport to file. The log is "perfect" in the sense that only requests that passes through route eg. /restaurant, /restaurant/id/, /user, are being logged with meta (good data).

When using winstonMongodb. I am receiving all of the above AND empty " / " routes. Basically doubling my log file with empty meta data from / and the other half is good data from above.
