Getting cloudWatch is a legacy winston transport. Consider upgrading

[surya-purohit]

I was working on v2.3.0 and everything was perfectly fine. But when I update winston-cloudwatch to v2.3.2. It started breaking and I saw a warning message displayed saying cloudWatch is a legacy winston transport. Consider upgrading.
After degrading to 2.3.0, it;s working again.

Code snippet:

import moment from 'moment';
import winston from 'winston';
import WinstonCloudWatch from 'winston-cloudwatch';

/**
 * Function to push logs to cloudwatch
 * @param  {String} options.region           Region of cloudwatch
 * @param  {String} options.secretAccessKey  Secret Access Key of the AWS user
 * @param  {String} options.accessKeyId      Access Key Id of the AWS user
 * @param  {String} options.logGroupName     Log Group Name on which the log is to be written
 * @param  {Object} options                  Options to log to cloudwatch
 * @return {Object}                          Logger Object
 */
export default function cloudwatchLog({
  region: awsRegion,
  secretAccessKey: awsSecretKey,
  accessKeyId: awsAccessKeyId,
  logGroupName,
}) {
  const logger = winston.createLogger({
    transports: [new WinstonCloudWatch({
      awsRegion,
      awsSecretKey,
      awsAccessKeyId,
      logGroupName,
      logStreamName: `${moment.utc().format('MM-DD-YYYY')}`,
      level: 'verbose',
      jsonMessage: true,
    })],
  });
  return logger;
}

In the other file I am importing this file and writing something like

const logger = require('./logger');
this.logger = logger(AWSConfig);
this.logger.info('I am done');

Once the logger is initialized, the warning is seen and while login like above, it gives error saying Callback is not a function

Thanks for this, I am currently working on a 3.0 version for winston-cloudwatch.

I suggest upgrading once it's done and then seeing if this issue is still valid.
