Why showing this “Papertrail is a legacy winston transport. Consider upgrading”

[Hasibul-Hasan]

I am using Winston version

"winston": "^3.2.1",
"winston-papertrail": "^1.0.5"

When I add
transports: [ new winston.transports.Papertrail({})]

I get

Papertrail is a legacy winston transport. Consider upgrading: - Upgrade docs: https://github.com/winstonjs/winston/blob/master/UPGRADE-3.0.md

why this message show and how do I stop showing this.

The master branch is a legacy transport for winston3. There is a v2 branch that is implemented in winston3 format. You can install it:
npm install https://github.com/kenperkins/winston-papertrail.git#v2 --save

There are a few papertrail connection differences between the old way and the new (winston3) way. It took me a while to find the details, but the readme that you can find here shows how to set up for Winston3.
