winston-transport this.once in the code causes app to crash.

[bobj82]

Please tell us about your environment:

• winston version?
  • winston@2
  • winston@3

./package.json

"dependencies": {
"comment":"irrelevant entries removed",
      "winston": "^3.3.3",
      "winston-mongodb": "^5.0.7",
      "winston-syslog": "^2.4.4"
   },

• _node -v outputs:_v16.13.0
• Operating System? macOS
• _Language? ES6/7

What is the problem?

I installed and configured winston-mongodb. When I tried to run the app, it crashed. Below are the details. I tried to fix it myself on the local copy, but it contiues to fail. So, I'm sending an issue instead of generating a pull request.

What do you expect to happen instead?

The app to start and send logs to mongodb.

Possible Solution:

I checked the core winston code. It includes a dependency for 'one-time'. So, I tried inserting it into my copy of winston-transport/index.js in the hopes of simply using a pull request. But, I apparently did it wrong because the code still fails. I'm willing to do the pull request if you tell me how to get it working.

Changes I Tried

winston-transport/package.json

"dependencies": {
                "one-time": "^1.0.0",
                "readable-stream": "^2.3.7",
                "triple-beam": "^1.2.0"
        },

winston-transport/index.js

const { LEVEL } = require('triple-beam');
const once = require('one-time');

Implementation Excerpts

./server.js

const logger = require('./logger.js');

./logger.js

const winston = require('winston');
const { transports, format } = winston;
require('winston-mongodb');

Did you ever get to the bottom of this, @bobj82 ? I;ve just run into the issue myself.

Not 100% sure if the transfer is correct, but if not, we can move it back.
